| abstract |
The invention relates to the polymer industry. It relates to compositions containing a propylene polymer, an adsorbent inorganic filler, such as talc or asbestos, and a stabilizing system comprising an organic sulfur compound and an antioxidant which is a sterically hindered phenolic ester of the acid. isocyanuric, in addition to optionally a deactivator for the additive (such as melamine or an epoxy resin). These antioxidant isocyanurates are preferred because they roughly double the effectiveness of the stabilizing system. |
