摘要:
Various vinylidene-containing polymers are obtained in the presence of a single-site catalyst. For example, the polymers include ethylene/isobutene copolymer, ethylene/propylene/isobutene terpolymer, ethylene/styrene/isobutene terpolymer, ethylene/α-methyl-styrene/sobutene terpolymer, propylene/isobutene copolymer, styrene/isobutene copolymer, and α-methyl-styrene/isobutene copolymer. These polymers may be used to formulate lubricant oils.
