Abstract
A process for producing a perfluoro copolymer, which comprises subjecting a perfluoro monomer having a carbon-carbon double bond with a different polymerization ability at each terminal of the molecule and perfluoro-2,2-dimethyl-1,3-dioxol to radical copolymerization.
Claims5
A perfluoro copolymer comprising the radical polymerization product of:
- 1-99% by weight of CF.sub.2 =CFOCF.sub.2 CF=CF.sub.2 ;
- and
- 1-99% by weight of perfluoro-2-2-dimethyl-1,3-dioxol.
