Abstract
A stabilizer system for styrenic polymers consisting essentially of (a) a benzotriazole;
(b) an oligomeric condensate of N,N'-(2,2,6,6-tetramethylpiperidyl) hexamethylene diamine and 2,4-dichloro-6-morpholino-1,3,5-s-triazine;
and (c) tris (3,5-d9-tert-butyl-4-hydroxybenzyl) isocyanurate with the proviso that the stabilizer system does not contain phosphites or phosphonites stabilizers. Further, an alternate embodiment is a stabilizer system for styrene polymers consisting essentially of (a) a benzotriazole;
(b) a hindered amine light stabilizer selected from the group consisting of (i) bis(2,2,6,6-tetramethyl-4-piperidinyl) sebacate; and (ii) bis-(1,2,2,6,6-pentamethyl-4-piperdinyl) ester of (3,5-di-tert-butyl-4-hydroxybenzyl)-butyl malonate; and (c) tris (3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate with the proviso that the stabilizer system does not contain phosphites or phosphonites stabilizers.
