    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: 70 to 95% ethylene is copolymerized with 30 to 5% vinyl isocyanate and/or isopropenyl isocyanate at a pressure between 200 and 2000 atmospheres and a temperature between 100 and 250 DEG C. in the presence of a free radical forming catalyst. A third comonomer, in amount up to 25% of the total monomers, may also be present; methyl, ethyl, butyl and ethylhexyl acrylate, vinyl acetate and propionate, methyl, ethyl, butyl and allyl vinyl ethers, styrene, acrylamide, methylolacrylamide the corresponding methacrylic compound, acrylic acid, methacrylic and maleic acid are specified. A solvent such as aliphatic, cycloaliphatic or aromatic hydrocarbons, halohydrocarbons, ethers, and ketones are preferred employed. Specified catalysts are azodiisobutyronitrile, methyl azodiisobutyrate, azo-bis-alpha-gamma-dimethylvaleronitrile, lauroyl, benzoyl, ditertiary butyl peroxides, D -butyl hydroperoxide and t-butyl perbenzoate-a mixture of an azo compound and an organic peroxide are especially advantageous.
