POLYMER AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide a substitute for polyisobutene and poly-α-olefin. SOLUTION: Various kinds of vinylidene-containing polymers can be produced in the presence of a single site catalyst. Examples of the polymers are ethylene/ isobutene copolymer, ethylene/propylene/isobutene terpolymer, ethylene/styrene/ isobutene terpolymer, ethylene/α-methylstyrene/isobutene terpolymer, propylene/ isobutene copolymer, styrene/isobutene copolymer and α-methylstyrene/isobutene copolymer. A lubricating oil can be produced by using these polymers.
