Abstract

A transparent polyblend is formed from PA0 (a1) 99.9-0.1% by weight of a methyl (meth)acrylate homopolymer or of a copolymer thereof with up to 20% by weight of units of alkyl (meth)acrylate having an alkyl radical of from 2 to 10 carbon atoms and up to 10% by weight of further comonomers or PA0 (a2) 99.9-0.1% by weight of a styrene or .alpha.-methylstyrene and acrylonitrile copolymer containing from 5 to 30% by weight of units of acrylonitrile or PA0 (a3) 99.9-0.1% by weight of a possibly impact-modified polyvinyl chloride homopolymer or copolymer with up to 20% by weight of comonomers and PA0 (b) 0.1-99.9% by weight of a cycloalkyl (meth)acrylate homopolymer or copolymer with up to 99.9% by weight of units of methyl methacrylate.
