ABSTRACT:
Disclosed is a polymer composition comprising (I) 60 to 99.8 wt. % of an amorphous copolymer comprising (a) units derived from perfluoro-2,2-dimethyl-1,3-dioxole and (b) units derived from at least one ethylenically unsaturated monomer selected from ethylene, tetrafluoroethylene, chlorotrifluoroethylene, and CF.sub.2 =CFOCF.sub.3, and (II) 0.2 to 40 wt. % of a compound having a hydrocarbon group containing at least one fluorine atom and at least one functional group selected from --OH, --SR, --COOH, --SO--, --SO.sub.2 --, --CONH--, --COO--CO--, --CONHCO--, --COO--, --CN, --NCO, --CO--, --HCOO--, --NH.sub.2 --, --NH--, .dbd.N, --SO.sub.3 H, --NHNH.sub.2, --CONH.sub.2, --CH.dbd.CH.sub.2, --CH.dbd.CH--, (RO).sub.n X.sub.3-n Si--, wherein R is a C.sub.1-5 alkyl group, n is a number of 0 to 3, and X is halogen or a C.sub.1-5 alkyl group. The polymer composition is useful for a plastic cladding of an optical fiber.
