POLYOLEFIN COMPOSITES, PROCESS FOR MAKING THE SAME, AND SHAPED ARTICLES MADE THEREFROM |
摘要 |
A process for the production of polyolefin composites comprising from 95 to 5 percent by weight of olefin homopolymer or interpolymer and from 5 to 95 percent by weight of filler which process comprises polymerizing one or more olefins in the presence of: A. a transition metal catalyst containing filler composition obtained by combining in a suitable diluent a dehydrated filler containing surface-hydroxyl groups with: i) an organoaluminum compound; ii) an organomagnesium compound which can be transformed into magnesium halide by halogenation; iii) a halogenating agent capable of halogenating the organomagnesium compound of ii); iv) a Group 4,5, or 6 transition metal compound; v) an organometallic reducing agent capable of reducing the Group 4,5, or 6 transition metal compound of iv); with the proviso that halogen containing components and the organomagnesium compound of ii) are employed in such quantities as to give a halogen:magnesium atomic ratio of at least 2; and B. a cocatalyst or activator for the transition metal catalyst.
