    Abstract: 1,146,653. Self-extinguishing polymeric compositions. BADISCHE ANILIN- & SODAFABRIK A.G. 7 July, 1966 [9 July, 1965], No. 30552/66. Headings C3C and C3P. A self-extinguishing composition consists of (a) a normally solid thermoplastic polymer of at least 50% by wt. of styrene which may be substituted, and less than 50% of at least one other copolymerizable compound having the group having intimately incorporated therewith (b) an organic bromide, having a plurality of bromine atoms attached to carbon atoms and the bromine atoms constituting more than 40% of the bromide, in such an amount that the composition has a bromine content of 0À1-5%, and (c) 0À01-5% of (a) of a polymer which is prepared from (i) a compound of formula where R 1 , R 2 , R 4 and R 5 are H, halogen or a C 1-4 aliphatic hydrocarbon radical and at least two of the above Rs are where R 7 is a C 1-4 linear aliphatic hydrocarbon radical and R 8 is H or R 7 , and R 3 and R 6 are H or halogen atoms; or (ii) a mixture of the above compounds and a compound of the same formula where R 1 is where R 7 and R 8 are as before and the remaining Rs are H or halogen atoms. The (a) polymer may be polystyrene, a copolymer of styrene and acrylonitrile together with optionally polybutadiene, or a polymer obtained by polymerizing styrene in the presence of polybutadiene. Polymer (c) may be prepared by dehydropolymerization of p- or m-diisopropylbenzene with optionally isopropylbenzene, or 1,2,4-tri- or 1,2,4,5-tetra-isopropylbenzene. The bromide (b) may be hexabromocyclododecane or tris - (2,3 - dibromopropyl) - phosphate. The composition may be made by dissolving the three components in methylene chloride or by extruding the three components, with optionally kaolin; or by polymerizing styrene in the presence of an aq. mixture of polyvinylpyrrolidone, sodium pyrophosphate, benzoyl peroxide and the above (b) and (c) components. The composition may also contain a foaming agent, e.g. pentane or methyl chloride, and may be formed into a foamed sheet or strand.

    Abstract: 1,147,684. Self-extinguishing thermoplastic compositions. BADISCHE ANILIN- & SODAFABRIK A.G. 19 July, 1966 [21 July, 1965], No. 32374/66. Headings C3C and C3P. A self-extinguishing composition consists of (a) a normally solid thermoplastic polymer or copolymer of styrene or substituted styrene which comprises at least 50% by wt. of the styrene or substituted styrene and less than 50% of one other olefinically unsaturated compound having intimately incorporated therewith (b) an organic bromide having a plurality of bromine atoms attached to carbon atoms and the bromine atoms making up more than 40% by wt. of the bromide, in such an amount that the composition has 0À1-5% wt. of bromine, and (c) 0À01-5% by wt. on (a) of a polymer consisting of repeating units of formula where R 1 is R 7 or XR 7 , R 7 is a C 1-6 aliphatic hydrocarbon, a phenylalkyl or phenyl radical which may be substituted by 1-5 chlorine atoms or a C 1-4 alkyl or alkoxy group and X is -O-, -CO- or -COO-; R 2 to R 6 are H, Cl or a C 1-4 alkyl or alkoxy group; and n is 3-200. The (a) polymer may be polystyrene or a copolymer of styrene and acrylonitrile. The (b) bromide may be hexabromocyclododecane or tris-(2,3-dibromopropyl) phosphate. The (c) polymer may be a polymerized diphenylmethane or ethylbenzene. The composition may be made by dissolving the three constituents in methylene chloride. The composition may also contain 3-10% of a foaming agent which is a volatile organic compound which does not dissolve the (a) polymer and has a boiling point below its softening point e.g. pentane, and may be foamed, e.g. in film form, using steam.

    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: 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.
