Patent number: 6700023Abstract: A new class of low temperature initiators has been found, enabling fluoroolefin polymerizations at relatively low temperatures. These initiators are diacyl peroxides which allow improved productivity and product properties, as well as more favorable reaction conditions.Type: GrantFiled: February 6, 2002Date of Patent: March 2, 2004Assignee: E. I. du Pont de Nemours and CompanyInventors: Robert Clayton Wheland, Ming-Hong Hung
