Abstract: PCT No. PCT/EP93/01222 Sec. 371 Date Nov. 22, 1994 Sec. 102(e) Date Nov. 22, 1994 PCT Filed May 17, 1993 PCT Pub. No. WO93/24561 PCT Pub. Date Dec. 9, 1993.An expandable styrene polymer comprising a) from 0 to 90% by weight of a styrene polymer or styrene copolymer other than b) contains at least 50% by weight of copolymerized styrene, b) from 10 to 100% by weight of a styrene/methacrylamide copolymer comprising from 0.5 to 50% by weight of at least one copolymerized N-substituted methacrylamide of the formula I I where R1 and R2 are identical or different and are hydrogen, C1- to C15-alkyl, C6- to C16-cycloalkyl or C6- to C20-aryl, it being possible, if R1 and R2 contain at least 2 carbon atoms, for at least 2 carbon atoms to be linked via hetero atoms, and c) from 1 to 15% by weight, based on the sum of a) and b), of an aliphatic C3- to C9-hydrocarbon and/or carbon dioxide as blowing agent.
