    Abstract: The reaction products of hexachlorocyclopentadiene with a dienophilic ester or ether are used as extreme-pressure lubricating oils (see also Division C5). Specified dienophiles are vinyl acetate, propionate, butyrate, hexanoate, 2-ethylhexanoate, oleate and palmitate; n- and iso-butyl, 2-ethylhexyl and lauryl acrylate; butyl crotonate and dibutyl and dilauryl maleate; and n- and iso-butyl, ethyl and 2-ethylhexyl vinyl ethers. The ester products may alternatively be prepared by reacting hexachlorocyclopentadiene with the dienophilic acid or nitrile followed by esterification. In examples, the dienophile is (1) acrylic acid and the product is esterified with a C8 fatty alcohol; (2) n-butyl, lauryl or octadecyl acrylate; (3) isobutyl vinyl ether; (4) vinyl propionate. ALSO:Extreme-pressure lubricating oils comprise a hydrocarbon-based lubricating oil, the reaction product of hexachloropentadiene with a dienophilic ester or ether and optionally a polymer of acrylic esters, methacrylic esters, isobutylene or styrene.

    Abstract: Polychloropropionic acid chlorides are prepared by reacting at least 3 moles of chlorine per mole of maleic anhydride at 80 DEG C.-250 DEG C. in the presence of a catalyst selected from barbituric acids, N,N1,N11,N111-tetrachloroglyoxaldiureide, N,N1-dialkyl ureido carboxylic acids (the alkyl groups containing 1-4 carbon atoms and the acids being monobasic aliphatic carboxylic acids with 1-18 carbon atoms), acylated quaternary ammonium compounds derived from a tertiary amine and acid chlorides of fatty acids containing 1-4 carbon atoms, benzoic acid amides, monoamides of monobasic aliphatic carboxylic acids having 1-18 carbon atoms (the amine portion being derived from ammonia, a primary or secondary mono-amine or a diamine of the saturated aliphatic, araliphatic, or cycloaliphatic series or the aromatic series having the amino groups attached to the aromatic ring), and diamides derived from diamines and monobasic aliphatic carboxylic acids having 1-18 carbon atoms. Many examples of suitable catalysts are given. The acid amide catalysts may be formed in situ, e.g. from the amine and the acid chloride or anhydride. In general 0.2%-10% of catalyst, based on maleic anhydride, is used. The chlorination may be effected in the liquid or vapour phase and may be continuous. The reaction product contains trito pentachloropropionic acid chlorides; the triis mainly a ,b ,b - and the tetrais mainly a ,b ,b ,b - with some a ,a ,b ,b -. Inert solvents may be used. The product acid chlorides or the corresponding polychloropropionic acids obtained by hydrolysis can be reacted with organic bases such as urea, dimethylurea, phenylurea, hydrazine, a -methylphenylhydrazine, aromatic or heterocyclic amines or with carbamic acid, phenthiazine, acridine, chlorophenolates, or naphtholates, to obtain insecticidal or herbicidal substances. Thus the products in examples are reacted to form 3,4-dichloroanilides.

    Abstract: Graft polymers are obtained by nitrosating all or part of the amide nitrogen atoms of copolymers with other unsaturated monomers of olefinically unsaturated aliphatic, cycloaliphatic and/or heterocyclic acylamines which are monosubstituted on the amide nitrogen atoms by alkyl, alkenyl aralkyl, cycloalkyl, cycloalkenyl, alkylene and/or cycloalkylene groups, and then grafting the nitrosated copolymers with olefinically unsaturated monomers. Unsaturated acylamines specified are the N- monosubstituted amides of acrylic, methacrylic and crotonic acids, N-monosubstituted monoamides of maleic and fumaric acids and esters thereof, N,N1-substituted diamides of maleic, fumaric, itaconic and mesaconic acids, N,N1-alkylene or -cycloalkylene substituted bis-acrylic, -methacrylic and -crotonic amides, N-methyl cyclohexen-1-yl carboxylamide, N,N1-methylene-bis-cyclohexenyl carboxylamide, N,N1-hexamethylene-bis-maleic monoamide and esters thereof, N-allyl acetamide, propionamide and butyramide, N,N1-diallylhexahydroterephthalamide, mono- and diureides of unsaturated acids, e.g. acrylic, methacrylic, maleic and fumaric acids, such compounds being substituted at one or more ureide nitrogen atoms, and barbituric acid derivatives substituted at the 5-position on the ring by a C2-C6 alkenyl group. Monomers specified for use either as comonomers with the unsaturated amides or as grafting monomers are acrylic and methacrylic acids and their nitriles, amides or ester with C1-C12 alkanols or cycloalkanols, styrene, methyl styrenes, ethylene, propylene, butene-1, butene-2, isobutylene, butadiene, isoprene, chlorobutadiene, vinyl acetate and propionate, vinyl and vinylidene chloride, vinyl ethers of C1-C12 alcohols, vinyl sulphonic acid, vinyl pyridine, pyrrolidone and carbazole and unsaturated polyesters. The nitrosation of the amide copolymers is accomplished by means of agents such as dinitrogen trioxide, nitrosyl chloride, alkyl nitrites and nitrous acid. The grafting of the unsaturated monomer on to the nitrosated copolymer may be effected in bulk, solution, emulsion or suspension, and may be accelerated by means of alkali metal carbonates and/or hydroxides, amines, e.g. triethanolamine, salts of iron, nickel, cobalt and manganese, peroxides or azodiisobutyronitrile. The Examples describe grafting of: (1) acrylic acid on to a nitrosated styrene-N-benzyl maleic monoamide copolymer, (2) a mixture of vinyl acetate and methyl methacrylate on to a copolymer as in (1), (3) butyl acrylate on to a nitrosated methyl methacrylate-N-(2-ethylhexyl)-maleic monoamide copolymer, (4) a mixture of vinyl acetate and acrylonitrile on to a nitrosated acrylonitrile-N,N1-methylene dimethacrylamide copolymer, (5) a mixture of styrene, butyl acrylate and acrylonitrile on to a nitrosated styrene-N,N1-methylene dimethacrylamide copolymer, (6) methyl methacrylate on to a nitrosated acrylonitrile-butadiene-N-benzyl maleic monoamide copolymer, (7) acrylonitrile on to a nitrosated styrene-butadiene-N-stearyl maleic monoamide copolymer, (8) methyl methacrylate on to a nitrosated styrene-N-allyl propionamide copolymer, (9) acrylonitrile on to a nitrosated N-methyl methacrylamide-N-isopropyl acrylamide copolymer, (10) acrylonitrile on to a nitrosated vinylidene chloride-styrene-N-lauryl maleic monoamide copolymer, (11) acrylonitrile on to a nitrosated methyl methacrylate-N,N-dimethyl maleic acid monureide copolymer, (12) a mixture of vinylidene chloride and vinyl pyrrolidone on to a nitrosated copolymer of styrene, N-cyclohexyl maleic monoamide and a polyester derived from maleic and phthalic acids and propylene glycol, (13) acrylonitrile on to a nitrosated methyl methacrylate-N-iso-octyl maleic monoamide copolymer, (14) acrylic acid on to a nitrosated styrene-N,N1-methylene dimethacrylamide copolymer, and (15) acrylonitrile on to a nitrosated vinyl chloride-vinyl propionate-N-allyl maleic amide copolymer. Specification 546,459 is referred to.

    Abstract: Propylene polymers contain as stabilizer a mixture of thianthrene or a derivative of thianthrene bearing one or more alkyl groups and/or halogen groups and/or a dioxotrimethylene group di-alkyl substituted in the 2-position, as substituent(s) together with a di - (alkyl - hydroxy - phenyl) - alkane, thiodi - (alkylphenol), di - alkyl - hydroxy - phenyl)-sulphone and/or a benzophenone substituted by one or more hydroxy and/or alkoxy groups. The propylene polymer may be a homopolymer or a copolymer with other olefines, e.g. ethylene, butene-1, butene-2 and pentenes. Optional ingredients include ultra-violet stabilizers, polyethylene, polyisobutylene and dyes, pigments and fillers, e.g. carbon black. The stabilizers used in the examples are 4,41-thio-di-(3-methyl-6-tert.-butylphenol) with thianthrene, dimethylthianthrene isomer mixture, 4,5-dichlorothianthrene or 1,2-(11,31-dioxo-21,21-diethyl -trimethylene) - thianthrene; methylene - di - (3-methyl-6-tert.-butylphenol) with dimethylthianthrene isomer mixture; and di-(3-tert.-butyl-4-hydroxyphenyl)-sulphone or o,p,p1-trimethoxybenzophenone with dimethyl - tert.-butylthianthrene isomer mixture. Other thianthrenes specified are 2,7- and 3,7-dimethylthianthrene and tert.-butylthianthrene. The stabilized polymers are suitable for producing films, sheets, housewares, casing and toys.
