PRODUCTION OFALPHA-OLEFIN POLYMERS

摘要

Ziegler polymerization of .alpha.-olefins is disclosedwhich is characterized by a solid catalyst component usedin the Ziegler-type catalyst. The solid catalystcomponent, Component (A), comprises Component (i) whichis a solid catalyst component for a Ziegler-type catalystcomprising Ti, Mg and a halogen; Component (ii) a siliconcompound of a formula:R1R2 3-nSi(OR3)nwherein R1 - R3 are each hydrocarbyl groupcharacterized by R1 which has a branched hydrocarbylgroup;Component (iii) a halogen compound of W or Mo; andComponent (iv) an organometal compound of a metal ofGroups I to IV of the Periodic Table.
