Polymerization catalyst |
摘要 |
A polymerization catalyst comprises a solid transition metal compound which has been ground with a Lewis Base, an organo-metallic compound of a non-transition metal and a cyclic polyene, preferably with a further quantity of the same, or a different, Lewis Base. The catalyst can be used to polymerize propylene to give a high yield of a polymer having a flexural modulus in excess of 1.00 GN/m2.
