    Abstract: Copolymers of ethylene with up to 50% by weight of one or more polymerizable ethylenically unsaturated compounds that are non-gaseous under the conditions of polymerization, at least 1% by weight of the total monomers being a carboxylic amide ethylenically unsaturated in the a ,b position to the carboxylic amide group and if desired, substituted on the amide nitrogen atom, are obtained by polymerizing, in the presence of free radical catalysts, at pressures from 50-600 atmospheres and at temperatures between 50 DEG and 200 DEG C. in a trickle-type reactor or a coil-type reactor, by contacting the ethylene with a thin layer of the polymerizable ethylenically unsaturated compound, which layer contains also the catalyst used. The copolymers produced by this method are waxy and may be readily emulsified in water. Carboxylic amides used are the amide of maleic acid, N-methylol derivatives of carboxylic acids, and alkyl ethers of the above. A long list of vinyl and vinylidene compounds suitable as co-monomers is supplied. Examples relate to the polymerization of ethylene with (1) acrylamide, (2) N-methylol methacrylamide, (3) N-methylol methacrylamide butyl ether, (4) crotonamide, (5) imide of maleic acid, (6) acrylamide and methyl acrylate, (7) methacrylamide and vinyl acetate, (8) N-methylol methacrylamide and ethyl acrylate, (9) N-methylol acrylamide methyl ether, or ethyl ether or hexyl ether, (10) monoamide of maleic acid, (11) N,N1-dimethylol diamide of maleic or fumaric acid, (12) N-hydroxyethyl monoamide of maleic acid.

    Abstract: One or more polymerizable olefins alone or with one or more other copolymerizable ethylenically unsaturated monomers are polymerized in the presence of a catalyst consisting of a mixture of (a) one or more metal chelate complex compounds of one or more metals of Groups Ib, IIb, IVa, Va, Vb, VIa, VIIa and VIII of the Mendeleeff Periodic Table and the rare earths and (b) one or more di- or higher multi-ethylenically unsaturated aliphatic cyclic hydrocarbons having from 5 to 12 carbon atoms in the ring. Long lists of suitable olefins, copolymerizable monomers and catalyst components are given. Those exemplified are: olefins-ethylene, propylene, isobutylene, styrene, 2 - methyl - 4,4 - dimethyl pentene - 1, butadiene and isoprene; copolymerizable monomers-acrylamide, maleic anhydride, vinyl acetate, maleic N-hydroxyethylmonoamide and methacrylic N-hydroxyethylmonoamide; metal chelates-AgI, CeIV, CoII, CuII, Hgic, MnII, MoIII, PbII, RhIII, TlI, VIII and ZnII acetylaceton-ates, CoII and MnII histidinates, MnII and RhIII o-amino phenolates, CuII and MnII aceto acetic acid ethyl ester complexes, Ag phenanthrolinate, CrIII glycinate, MnII anthranilate, NiII aceto-acetic acid-3-methylbutene-(1)-ol-(3)-ester, NiII acetoacetic acid propargyl ester, NiII salicylaldehyde, and SbV tetrachloroacetyl acetonate; unsaturated aliphatic cylic hydrocarbons-cyclopentadiene, cyclohexadiene, cyclopentatriene, cyclooctadiene - 1,3, cyclooctadiene - 1,4, cyclooctadiene - 1,5, cyclooctatetraene, and cyclododecatriene - 1,5,9- (trans, trans, trans). In the examples the polymerization is effected in bulk or in benzene or cyclohexane solution. Organic halogen compounds may be added to the polymerization mixture, of which chloroform and hexachloroethane are exemplified. In one example cyclopentadiene acts both as the catalyst component (b) and as a comonomer. The polymers formed are precipitated with methanol.

    Abstract: 1,154,699. Grafted isobutylene polymers. BADISCHE ANILIN- & SODA-FABRIK A.G. 21 Oct., 1966 [23 Oct., 1965], No. 47232/66. Heading C3G. A 1,3-diene is grafted on to the reaction product of a halogenated isobutylene polymer with a Lewis acid. The diene is e.g. butadiene, isoprene or chloroprene; a mixture of a diene with styrene, α-methyl styrene or a vinyl ether such as ethyl, n-propyl, isobutyl or n-hexyl vinyl ether may be used. The isobutylene polymer, which is a homopolymer, or a copolymer of at least 80% isobutylene with butadiene, isoprene, styrene, α-methyl styrene or a vinyl ether, is halogenated conventionally. A list is given of suitable Lewis acids and of Ziegler- Natta catalysts which may be used for the polymerization. The graft polymers may he vulcanized with conventional agents and then compounded with fillers. In Examples 1 and 2 a brominated polyisobutylene is dissolved in toluene and reacted with AlCl 3 prior to grafting with butadiene and isoprene respectively, using Et 3 AlCl and cobalt (II) acetylacetonate as catalyst. Examples 3 to 18 describe processes in which a chlorinated isobutylene-isoprene rubber is dissolved in an n-hexane/toluene mixture and reacted with TiCl 4 , ZrOCl 2 , TiBr 4 , TiI 4 , AlBr 3 , HClO 4 , SnCl 4 , NbCl 5 , TaCl 5 , VCl 4 , MoCl 4 , palladium (II) hydrochloride, gold (III) hydrochloride, platinum (IV) hydrochloride or FeCl 3 and grafted with butadiene using AlEt 3 and cobalt (II) acetylacetonate as catalyst. In Example 19 a brominated isobutyleneisoprene rubber is dissolved in a p-diisopropyl benzene/pentane mixture and grafted with butadiene using AlBr 3 as the Lewis acid and AlEt 3 and chromium (III) acetyl acetonate as catalyst.

    Abstract: Crude olefin polymers containing inorganic catalyst residues are purified by treating a solution obtained by the polymerization process or by subsequent dissolution of a crude polymer in an organic solvent at elevated temperature, with a precipitate to precipitate the inorganic catalyst residues, adding an inorganic surface-active compound of porous structure having a large internal surface to remove the solid substance and then separating mechanically. Specified olefins are ethylene, propylene and ethylene - alpha - butylene mixture. Specified solvents are xylene, ethyl benzene, diethyl benzene isopropyl benzene, and di- and triisopropyl benzene. Specified surface - active compounds are gamma-aluminium oxide, silicon dioxide, kieselguhr, bleaching earths, bentonite and montmorillonite; these may also be added before or during polymerization. Water, preferably in the form of steam or superheated steam, is the preferred precipitant.

    Abstract: Polymers of olefins are obtained by the use as sole catalystic material of metal chelates of Group IVb, Vb, VIb, VIIb, or VIII metals and b -diketones, b -ketocarboxylic esters, acetylacetonimide, salicylaldehyde, chloromalondialdehyde, a -hydroxypropionic acid, dihydroxymalonic acid, histidine or 1,3-diaminobutyric acid. Copolymers with a wide variety of monomers may be obtained. Optional ingredients are catalyst carriers, such as charcoal, carbon black, aluminium oxide, silica gel and aluminium silicate, and organic amines or carboxylic acids or amides. The reaction may be in bulk, in water, or preferably in an organic medium. Most of the examples illustrate the use of acetylacetonate complexes. The products may be of high crystallinity or enhanced 1,4-cis or 1,4-trans structure.
