    Abstract: 1,137,925. Copolymers of etherified methylol- (meth)-acrylamide. BADISCHE ANILIN- & SODA-FABRIK A.G. 7 April, 1966 [10 April, 1965; 26 May, 1965], No. 15501/66. Heading C3P. In a multi-stage process for preparing derivatives of amide copolymers (A) 0À9-1À2 moles of (meth)-acrylamide, 0À9-1À2 moles of paraformaldehyde (calculated as monomer), at least 0À9 moles of an (oxa)-alkanol having up to 8 carbon atoms and 0À001-0À5 moles of a tertiary aliphatic or cycloaliphatic monoamine having up to 12 carbon atoms are reacted at 50-100‹ C.; (B) then at least 101 equivalent per cent, based on said monoamine, of an α,#-ethylenically unsaturated mono- or di-basic carboxylic acid and/or an (oxa)-alkyl half-ester of such a dibasic acid having up to 9 carbon atoms in the (oxa)-alkyl radical is added and the mixture kept at 80-140‹ C.; (C) then any remainder of the said carboxylic acid or half-ester, and an (oxa)-alkyl ester of (meth)-acrylic acid having up to 20 carbon atoms in the (oxa)-alkyl radical and/or an (alkyl)-vinyl benzene having up to 12 carbon atoms and, if desired, other comonomer are added and copolymerization is carried out using an aliphatic or cycloaliphatic azo compound or an organic peroxide having a half-life of 0À1-30 hours at 85-110‹ C. as polymerization initiator. Polymerization is generally effected in an organic solvent which may be an excess of the (oxa)-alkanol used in step (A) or benzene or an alkyl benzene. In step (A) an oxygen-containing atmosphere is used and in step (B) a polymerization inhibitor is desirably included, e.g. phenothiazine, hydroquinone, methylene blue, nitrosophenol or mdinitrobenzene. The initiator used in step (C) may be azodiisobutyronitrile, azodiisobutyramide, azodicyclohexylcarbonitrile, cumene hydroperoxide, dibenzoyl peroxide, dilauroyl peroxide, t - butyl permaleate, t - butyl hydroperoxide, 2,2 - bis - (t - butyl peroxy)- butane or t-butyl perbenzoate; the initiator may be added continuously during polymerization. A regulator, e.g. t-dodecyl mercaptan, may be included in the polymerization reaction. In the examples, the following monomers are used: acrylamide, maleic acid, acrylic acid, styrene, 1,4-butane-diol monoacrylate and also, in some cases, 2-ethyl hexyl acrylate; the (oxa)-alkanol being n-butanol and the amine being N,N - dimethyl - (# - hydroxyethyl)- amine. The polymers obtained in the invention are useful in coating compositions, stoving lacquers, impregnants and adhesives.

    Abstract: 1,161,095. Coatings. BADISCHE ANILIN- & SODA-FABRIK A.G. 25 Oct., 1966 [26 Oct., 1965], No. 47815/66. Heading B2K. [Also in Divisions C3, D1 and D2] Hardboard is coated with an organic solvent solution, containing formaldehyde and a copolymer of butanediol acrylate acetyl acetate, styrene, 2-ethylhexyl acrylate, N-butoxymethylmethacrylamide, and acrylic acid, the coating then being dried and hardened by heating. An aqueous dispersion containing formaldehyde and a copolymer of butanediol acrylate acetyl acetate with styrene may be applied to hardboard. Steel and glass sheets are coated may be with an organic solvent solution containing formaldehyde and a copolymer of butanediol acrylate acetyl acetate, 2-ethylhexyl acrylate and styrene.

    Abstract: Polymers used in sizing paper (see Division D2) are derived from imidazole derivatives having an ethylenically unsaturated polymerizable group on the ring nitrogen (monomer I), with or without one or more of the following comonomers: up to 95% by weight of one or more polymerizable unsaturated compounds containing in the molecule a carbonamido group with one or two substituents on the nitrogen atom (monomer II); up to 50% by weight of one or more further water-soluble monomers (monomer III); and up to 30% by weight of one or more water-insoluble monomers (monomer IV). Polymers referred to in the examples are: homopolymers of N-vinylimidazole (Examples 1-7, 9 and 10); binary copolymers of N-vinyl-imidazole with N-vinylcaprolactam (Examples 11(b) and (c), 12(a) and (b) and 14(b)), or N-vinyl-pyrrolidone (Example 13(e)), or acrylonitrile (Examples 13(a) and (c)), or acrylic acid (Example 13(b)), or ethyl acrylate (Example 16(a)); ternary copolymers of N-vinylimidazole with N-vinylpyrrolidone and N-vinylcaprolactam (Example 14(a)), or N-vinyl-pyrrolidone and acrylonitrile (Examples 11(a) and 13(d)), or dimethylacrylamide and acrylonitrile (Example 15), or N-vinylcaprolactam and vinyl acetate (Example 17); a ternary copolymer of butyl acrylate, acrylonitrile and vinylimidazole quaternized with dimethyl sulphate (Example 8); and a quaternary copolymer of N-vinylimidazole, N-vinylcaprolactam, N-vinylpyrrolidone and ethyl acrylate (Example 16 (b)). Specification 897,804 is referred to.ALSO:Paper is stock-sized or surface-sized with a water-soluble homopolymer or copolymer derived from one or more compounds of the type of imidazole having an ethylenically unsaturated polymerizable group on the ring nitrogen (monomer I). The copolymer may contain up to 95% by weight of one or more polymerizable unsaturated compounds containing in the molecule a carbonamido group with one or two substituents on the nitrogen atom (monomer II), or up to 50% by weight of one or more further water-soluble monomers (monomer III), or up to 30% by weight of one or more water-insoluble monomers (monomer IV). The Specification includes lists of suitable monomers. The paper may also be sized with rosin and alum, and may contain fillers, e.g. china clay. Specification 897,804 is referred to.
