ABSTRACT:
Copolymers of styrene or a-methylstyrene and at least one comonomer, containing crosslinked elastomer particles, can be light-stabilized by modifying the elastomer particles by copolymerization with a suitable derivative of a sterically hindered amine. The modification is preferably carried out by graft polymerization, the elastomer used preferably being polybutadiene.
