Abstract: Continuous production of styrene polymers which contain an expanding agent and which are in the form of granules by extrusion of a mixture of a melt of the polymer with the expanding agent and rapid cooling of the extruded mixture, wherein excess expanding agent is first mixed with the melt and then the excess of expanding agent is evaporated. In this way both the production of a homogeneous mixture and the cooling of the mixture prior to extrusion to temperatures just above the softening point of the mixture are facilitated.

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.

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.
