发明名称 Process for polymerizing cyclopentene
摘要 Cyclopentene homopolymers and copolymers are prepared by polymerizing cyclopentene alone or with one or more copolymerizable cycloolefins in the presence of (1) a catalyst comprising (a) at least one compound selected from the group consisting of dialkylaluminum iodides, alkylaluminum diiodides and mixtures of trialkylaluminum compounds with elemental iodine and (b) at least one solvent-soluble tungsten compound, (2) at least one nonconjugated acyclic olefin having at least one hydrogen on each double-bonded carbon atom, and (3) a solvent for the tungsten compound comprising at least one alkyl ester of a saturated carboxylic or dicarboxylic acid. Catalyst component (a) is charged before catalyst component (b). Use of the ester solvent causes a brief induction period allowing excellent process control and resulting in substantially gel-free polymers.
