ABSTRACT:
A compatible polymer blend consisting of: (I) 0.1-99.9% by weight of a polymerisate P1, which is formed from monomers of formula I: ##STR1## wherein R.sub.1 is hydrogen or methyl, and (II) 99.9-0.1% by weight of copolymerisate P2, which is formed from (a) 5-40% by weight of cyclohexyl methacrylate, (b) 30-70% by weight of a methacrylic ester of formula II: ##STR2## wherein R.sub.2 is methyl or ethyl, (c) 10-50% by weight of a methacrylic ester of formula III: ##STR3## wherein R.sub.3 is a hydrocarbon group having 4-18 carbon atoms, and (d) 0-10 parts by weight of a monomer M which is copolymerizable with monomers of (a)-(c), yet different from these monomers.
