Improving heat aging of grafted polyolefins using zinc mercapto compounds |
摘要 |
<p>A combination of about 0.5% to about 5% of a zinc salt of 2-mercaptobenzimidazole, 2-mercaptotoluimidazole or 2-mercaptobenzothiazole and about 0.05% to about 0.5% of a hindered phenol compound, based on the total weight of the composition, is used to improve heat aging of graft copolymers having a backbone of a propylene polymer material and side chains of polymerized styrenic and/or acrylic monomers.</p> |
