    Abstract: 1,149,745. Copolymers. BADISCHE ANILIN- & SODA-FABRIK A.G. 26 Aug., 1966 [28 Aug. 1965], No. 38301/66. Heading C3P. Copolymers containing chlorine may be prepared by copolymerizing a 1,3-diene with 2- chloroprene under conventional polymerization conditions. The diene may be butadiene or isoprene, and other monoolefinically unsaturated compounds, e.g. vinyl esters, ethers and ketones, unsaturated acids and esters, amides, nitriles and anhydrides thereof, and vinyl aromatic and heterocyclic compounds, may also be copolymerized. Polymerization may be effected in the presence of Ziegler catalysts, peroxides and azo compounds, redox systems, transition metal chelates and mixtures of cobalt and nickel carbonyls with aluminium halides and complexing agents or alkyl aluminium compounds; in organic liquid media or in aqueous emulsion or suspension in the presence of conventional emulsifiers and suspending agents. Extensive lists of comonomers, catalysts and conventional media and agents are given and examples describe the copolymerization of (1) butadiene and (2) isoprene with 2-chloropropene in n-hexane and paraffin oil in the presence of cobalt acetylacetonate and diethyl aluminium chloride, of (3) butadiene and 2-chloropropene in aqueous dispersion in the presence of a sodium paraffin sulphonate and gold acetylacetonate, and of (4) butadiene, 2-chloropropene, styrene and acrylonitrile in aqueous dispersion in the presence of a sodium paraffin sulphonate and potassium persulphate.

    Abstract: 1,139,431. Stereoblock polybutadienes. BADISCHE ANILIN- & SODA-FABRIK A.G. 13 May, 1966 [15 May, 1965], No. 21258/66. Heading C3P. Stereoblock polymers of butadiene are made by reacting (1) a catalyst containing hydrocarbon solution of uncrosslinked polybutadiene made by polymerizing butadiene with a catalyst comprising a compound of a transition metal of Groups IV to VIII of the Mendeleeff Periodic System and an alkyl metal compound until the polymer has a K-value of from 20 to 80, with (a) a similar solution of uncrosslinked polybutadiene of different configuration, until the resulting polymer has a K-value of 90 to 120. At least one of the solutions may contain unreacted butadiene. The solutions (1) and (2) are preferably effected below 0‹ C., and the reaction between - 5‹ and + 30‹ C. The specification contains numerous examples of catalysts which give rise to polybutadienes of different and opposite configurations. The polymers may be vulcanized.

    Abstract: 1,157,697. Copolymers of dienes and lactams. BADISCHE ANILIN- & SODA-FABRIK A.G. 25 Nov., 1966 [27 Nov., 1965], No. 52870/66. Heading C3P. Copolymers of lactams and dienes are made by copolymerizing a mixture of the monomers in the presence of a catalytic amount of a metal of columns IA and IIA of the Periodic Table of Elements appearing in Handbook of Chemistry and Physics, 47th Edition, e.g. Li, Na, K, Mg, and Ca. Specified lactams are pyrrolidone, caprolactam, capryllactam, oenantholactam, and laurolactam. Suitable dienes are butadiene, isoprene, chloroprene, 2,3-dichlorobutadiene, 2-phenylbutadiene, 2,3-diphenyl-butadiene, 2- ethoxybutadiene, and 2,3-diethoxybutadiene. Solvents such as hydrocarbons and/or ethers may be present during copolymerization. The copolymers may be tough elastic solids or highly viscous oils. The latter may be used as additives for rubbers, polyethylene, or, polypropylene.

    Abstract: Ethylenically unsaturated monomeric compounds are polymerized in bulk or in inert organic solvent solution using a catalyst comprising solely at least one p complex of a metal of Group Ib, Vb, VIb or VIIb or of an element having an atomic number from 27 to 78 of Group VIII of the Periodic system, with or without an organic halogen compound or an organic amine. The metal p complexes have the following general formulae:-(Olefine)mMe; (Olefine)mMeXn; (Olefine)mMeXnL0 and (Olefine)mMe(aromatic), where Me is the metal atom; m, n, o are integers; L are neutral ligands, e.g. amines or phosphines and X is a monovalent negatively charged radical, e.g. Cl-, NO3-, CH3COO-, ClO4-, Br- or I-. The term "olefine" includes radicals derived from olefines and the "aromatic" may be benzene and its derivatives. The catalytic activity may sometimes be increased by adding smalll amounts of organic, preferably aliphatic, halogen compounds or organic amines. In the examples:-(1) butadiene is polymerized in bulk using nickel (o)-bis-cyclooctadiene-1,3 or monomethylcyclopentadienyl manganese benzene; (2) isoprene is polymerized in benzene using allyl nickel bromide or diallyl nickel; (3) methyl methacrylate is polymerized using dicyclopentadienyl molybdenum dibromide or [nickel(P(C6H5)3)2]C2H4; (4) styrene is polymerized using silver (cyclo-octadiene-1,5) nitrate and pyridine; (5) styrene and vinyl acetate are copolymerized using copper (cyclo-octadiene-1,3) chloride; (6) acrylic acid and propylene (or isobutylene) are copolymerized in cyclohexane using platinum (hexadiene-1,5) chloride; and (7) butadiene and dibutyl fumarate are copolymerized in benzene using ruthenium (cyclohexadiene-1,3) benzene, or dicyclopentadienyl vanadium iodide, or cyclo-octatetraene chromium di-iodide.
