Abstract

1410266 Styrene polymer/brominated thiochromanone compositions CHEMISCHE WERKE HULS AG 27 April 1973 [28 April 1972] 20072/73 Headings C3C and C3P An expandable moulding composition consists of an expandable styrene homopolymer or copolymer containing not more than 50% by wt. of comonomer units which contains a blowing agent (e.g. which is a gaseous or liquid organic compound which does not dissolve the polymer and whose b.p. is below the temperature at which the polymer softens, and a flameproofing agent which is at least one halogen derivative of thiochromanone of formula where X 1 , X 2 and X 3 are Cl, Br or H provided that at least one is Br and not more than one is H, and n is 0-2, and which is present in such an amount as to give a bromine content of 0.1-5% by wt., relative to the styrene polymer. In the examples polystyrene containing pentane as blowing agent was mixed with 1-oxy-3,3,6-tribromo - thiochromanone or 3,3,6 - tribromothiochromanone and optionally dicumyl peroxide as a synergistic agent to form expandable flameproofed polystyrene beads.
