    Abstract: Polymers of vinyl methyl ketone or isopropenyl ketone or the cyclization products of such polymers are heated to a temperature of from 30 DEG C. to 800 DEG C. in the presence of a metal halide of a metal of Groups IIIA, IVB, VB, VIB, or VIIB of the Periodic Table (defined) or of iron or zinc in the presence of a dehydrogenating agent, to produce aromatized high-molecular weight compounds. Copolymers of the above ketones containing at least 50% by weight of ketone may also be used. The cyclization products are formed by intramolecular condensation by the action of acid or alkali. The treatment of copolymers with styrene, vinyl chloride, butadiene, isoprene, acrylonitrile, and methacrylonitrile are exemplified.

    Abstract: A self-extinguishing composition comprises (a) a styrene polymer, (b) an organic chlorine or bromine compound used in such amount that the chlorine content of the composition is 3-10% or the bromine content is 1-5%, and (c) 0.05-5% of a metal chelate compound of a metal of Groups Ib, IIb, IVb, Va, VIb, VIIb or VIII of the Periodic Table. The polymer may be polystyrene or a styrene copolymer containing at least 50 mol. per cent styrene and acrylonitrile, an ester of acrylic or methacrylic acid with a C1- 8 alcohol, vinyl carbazole, butadiene or 0.01-0.5% divinylbenzene. The chelate compound may be an acetylacetonate of copper, zinc, mercury, titanium, chromium, molybdenum, manganese, iron or cobalt, ethyl acetoacetate and copper, nickel salicylaldehyde, chromium anthranilate, or may be one of the said metals and a b-diketone, a b-ketocarboxylic ester, a hydroxyaldehyde or an aminocarboxylic acid. The organic chlorine compound may be a chlorinated diphenyl. The composition may also contain 2-20% of an expanding agent, e.g. a gaseous or liquid hydrocarbon or chlorofluorohydrocarbon. In an example, styrene is bead polymerized in water with polyvinylpyrrolidone, a chlorinated paraffin, pentane and a chelate compound, to produce a foam; styrene is polymerized in petroleum ether with hexabromocyclododecane and the chelate compound; films are prepared from a solution of the composition in methylene chloride and are then expanded.
