    • The invention is directed to weatherable pigmented extruded polystyrene molded or extruded foam articles for use in outdoor applications or applications which require high weatherfastness. The weatherfast pigmented polystryene compositions can be prepared by incorporating by extrusion or molding (a) a foam polystyrene homopolymer or copolymer (b) at least one compound selected from an light absorber, (c) at least one compound selected from the group consisting of low molecular weight hindered amine light stabilizer, (d) at least one compound selected from the group consisting of high molecular weight hindered amine light stabilizer, (e) at least one pigment and (f) optionally carbon black, wherein the expanded polymer foam shows a Δ E color change under xenon weathering over a period of 3000 hours of less than about 3.0.
    • 本发明涉及用于室外应用或需要高耐候性的应用的耐候性着色挤出聚苯乙烯模制或挤出泡沫制品。 耐候性着色的聚苯乙烯组合物可以通过挤出或模制(a)泡沫聚苯乙烯均聚物或共聚物(b),至少一种选自光吸收剂的化合物,(c)至少一种选自低聚物 分子量受阻胺光稳定剂,(d)至少一种选自高分子量受阻胺光稳定剂,(e)至少一种颜料和(f)任选的炭黑)的化合物,其中发泡聚合物泡沫体显示出 氙气风化下的Delta E颜色变化在3000小时以内,小于约3.0。
