Abstract: Polymers of ethylenically unsaturated monomeric compounds are prepared using a catalyst comprising (a) at least one metal chelate compound of a Group IVb, Va, Vb, VIb, VIb or VIII metal (for Periodic Table see Handbook of chemistry and Physics) and a b -diketone, b -ketocarboxylic ester, ester of diacetoacetic acid, amino acid having 2 to 6 carbon atoms, salicylaldehyde, chloromalonodialdehyde, o-amino phenol, o-aminobenzoic acid or 2,21-hydroxyazobenzene and (b) at least one aliphatic, aromatic or heterocyclic chlorine, bromine or iodine compound having 1 to 12 carbon atoms. The catalyst contains component (a) in an amount between 0.001 and 5% by weight based on the weight of monomeric compounds, and 0.01 to 50 parts of component (b) to 1 part of component (a).  The polymerization may be in bulk or the monomers may be dissolved or suspended in inert auxiliary liquids for the polymerization such as hydrocarbons, ethers, alcohols and ketones.  Lists of catalyst components (a) and (b), monomers and auxiliary liquids are given.  In the Examples: (I) styrene is homopolymerized using carbon tetrachloride and one of the following: manganic acetylacetonate, manganic anthranilate, manganic acetoacetic ethyl ester, cobaltic acetylacetonate, cobaltic histidinate, cobaltic acetoacetic ethyl ester, chromic glycinate and molybdenum acetylacetonate; (2) styrene is homopolymerized using manganic acetylacetonate and one of the following: bromobenzene, hexachloroethane, chlorobenzene, 1,3,5-trichlorobenzene, cyanuric chloride, trichloroethylene, 1,2-dibromoethane, carbon tetrachloride, pentachloropropanol, n-amylchloride, a -bromocaproic acid and 2-amino-5-iodopyrimidine; (3) ethylene is copolymerized with vinylethylether using carbon tetrachloride and manganic acetylacetonate; (4) diisobutylene is copolymerized with acrylic acid using hexachloroethane and manganic acetylacetonate; (5) propylene is copolymerized with acrylamide and ethyl acrylate using amyl chloride and nickelous acetoacetic propargyl ester; (6) styrene is copolymerized with vinyl chloride using manganic anthrilate and amyl chloride; (7) butadiene is copolymerized with dibutyl fumarate using manganic acetylacetonate and chloroform; (8) styrene is compolymerized with vinyl acetate using cobaltic anthranilate and 1,4-dichlorobutane; (9) butadiene is copolymerized with acrylic acid using nickeleous acetylacetonate and butyl chloride; (10) ethylene is homopolymerized using cobaltic acetylacetonate or cobaltic acetylacetonimide and carbon tetrachloride or amyl chloride; (11) butadiene or isoprene is homopolymerized using manganic diacetoacetic ethyl ester and n-lauryl chloride; (12) methylmethacrylate is homopolymerized using cobaltic salicylaldehyde and carbon tetrachloride; (13) vinylisobutyl ether is homopolymerized using chloroform and manganic ortho-aminophenolate, antimony tetrachloroacetylacetonate or titanium dichloroacetylacetonate; (14) acrylic acid is homopolymerized using carbon tetrachloride and manganic acetylacetonate; (15) acrylamide is homopolymerized using cobaltic chloromalonodialdehyde and bromoform; (16) N-methylol methacrylamide, N-vinylimidazole or N-vinyl-carbazole are homopolymerized using vanadium acetylacetonate, manganic acetoacetic ester and n-amyl chloride and (17) styrene is copolymerized with acrylonitrile using methylene chloride and manganic 2,2-hydroxyazobenzene.
