The catalytic converter for solution polymerization of vinyl chloride - ethylene copolymer production which features polymerization catalytic converter for vinyl chloride - ethylene copolymer production

摘要

PROBLEM TO BE SOLVED: To provide a new polymerization catalyst for producing a vinyl chloride-ethylene copolymer, which permits the production of a vinyl chloride- ethylene copolymer having a high ethylene unit content under the conditions of a low reaction pressure during polymerization, and a process for producing a vinyl chloride-ethylene copolymer using the catalyst. ;SOLUTION: The polymerization catalyst for producing a vinyl chloride- ethylene copolymer comprises pentamethylcyclopentadienyltitanium trimethoxide and methylaluminoxane.;COPYRIGHT: (C)2001,JPO
