ABSTRACT:
A compatible, single-phase, polyblend comprising
I) a polymer which is a polycarbonate, polyvinyl chloride, or polyvinylidene fluoride, and
II) a copolymer comprising from 40 to 99.99 percent by weight of
A) a monomeric ester formed between acrylic acid or methacrylic acid and a C1-C10 alcohol, and from 0.01 to 60 percent by weight of
B) a monomer of the formula ##STR1## wherein R.sub.1 is hydrogen or methyl, Y is oxygen or -NR.sub.2 - where R.sub.2 is hydrogen or alkyl, and Z is
i) a 2-hydroxyphenyl benzotriazole,
ii) a 2-hydroxybenzophenone or 2-hydroxyacetophenone,
iii) an alpha-cyano-beta,beta-diphenyl, and
C) optional other monomers.
