PRODUCTION OF FLUOROCOPOLYMER

摘要

PURPOSE:To obtain a fluorocopolymer having a small temperature dependency of melt viscosity by copolymerizing tetrafluoroethylene with fluoromonovinyl ether in the presence of fluorodivinyl ether. CONSTITUTION:40-98mol% tetrafluoroethylene is copolymerized with 1-40mol% fluoromonovinyl ether of the formula: CF2=CFOCH2Rf (wherein Rf is perfluoroalkyl) and 1-20mol% fluorodivinyl ether of the formula: CF2=CFOCF2 CF2OCF=CF2.
