초록

A process for the polymerization of olefins in the presence of hydrogen comprising contacting the olefin, a cyclopentadienyl compound and a catalyst comprising a transition metal compound at polymerization conditions.

대표청구항 ▼

A process comprising contacting at least one mono-1-olefin, a catalyst, and hydrogen in a first step to produce a first polymer; wherein said catalyst comprises a transition metal compound and wherein the transition metal of said transition metal compound is selected from the group consisting of titanium, zirconium, and vanadium; and contacting said at least one mono-1-olefin, said catalyst, and a cyclopentadienyl compound in a second step to produce a second polymer; wherein said cyclopentadienyl compound is selected from the group consisting of cyclopentadiene, dicyclopentadiene and cyclopentadienyl compounds substituted with hydrocarbyl or hydrocarbyl silyl radicals having from 1 to 10 carbon atoms; and wherein said contacting in said first step and said second step is under polymerization conditions.
