Abstract

Process for obtaining photodegradable polyamide compositions comprising a condensation copolymer characterized in that acetone carbonyls groups are included in the copolymer, either in the polymer backbone or on one side in a position immediately adjacent to the polymer backbone, in an amount sufficient to cause accelerated photodegradation of the condensation polymer to a brittle or reliable condition when exposed to ultraviolet light.
