| 摘要 |
The invention relates to a composition containing a polymer and at least one hindered-amine light stabilizer (HALS), and a bridged amine compound having at least one N-bridgehead, characterized in that the polymer is an ethylene/ alpha -olefin/nonconjugated polyene copolymer rubber a with a build in nonconjugated polyene amount of at least 1 % by weight with respect to the weight of the copolymer. The nonconjugated polyene is preferably 5-ethylidene-2-norbornene, vinylnorbornene, dicyclopentadiene or combinations thereof.
