ABSTRACT:
A photodegradable polymer composition comprising 50 to 99 weight percent based on the total weight of photodegradable polymer composition of a thermoplastic addition polymer and 1 to 50 weight percent based on the total weight of the photodegradable polymer composition of a photodegrading agent, said photodegrading agent being a polyketone which is a linear copolymer consisting of units of --CO(C.sub.2 H.sub.4)-- and units --CO(B')-- where B' is derived from olefinically unsaturated hydrocarbon selected from the group consisting of CHR.sub.4 .dbd.CHR.sub.5 (I) and CH.sub.2 .dbd.C(R.sub.6)(CHR.sub.7 R.sub.8) (II), wherein R.sub.4 is a hydrocarbyl group, R.sub.5 is hydrogen or a hydrocarbyl group, R.sub.6 is a hydrocarbyl group, and R.sub.7 and R.sub.8 are individually hydrogen or hydrocarbyl groups.
