Abstract: 1,163,730. Moulding compositions. BADISCHE ANILIN- & SODA-FABRIK A.G. 13 Jan., 1967 [15 Jan., 1966], No. 1928/67. Headings C3C and C3P. Particulate moulding compositions consisting of a mixture of a styrene polymer and an expanding agent, wherein the particles contain 0.001-0.6% by weight of the styrene polymer, in homogeneous distribution, of a brominated polymer of a 1,3-diene may be made by polymerizing monomeric styrene in a heating process, with or without other monomers, in the presence of an expanding agent and the brominated polymers and then cooling, or polymerizing styrene in aqueous suspension and adding the bromine compounds, with or without the expanding agent during polymerization at a point when the particles no longer divide. Exemplified styrene polymers are polystyrene and styrene copolymers which contain at least 50% by weight of styrene units. The copolymerization units include 2, methylstyrene, acrylonitrile, methacrylonitrile, esters of acrylic or methacrylic acids and alcohols having 1-8 C, esters of fumaric acid and alcohols having 1-8 C, vinyl pyridine, N-vinyl compounds such as N-vinyl carbazole, butadiene or small amounts of divinylbenzene. Examples of suitable brominated polymers of 1,3-dienes are the bromination products of butadiene polymers, isoprene polymers and chloroprene polymers. Specific examples of suitable brominated polymers are 1,2,5,6 - tetrabromocyclododecane, brominated cyclo-octadiene - (1,5), 1,2,5,6,9,10- hexabromocyclododecane, brominated 1-vinylcyclohexene-(3) or brominated polybutadiene which has a linear structure. Bromination is carried out using elemental bromine, the reaction being carried out in solution or dispersion. Suitable solvents are n-butanol, CS 2 , glacial acetic acid or CCl 4 .
