ABSTRACT:
An optical fiber cladding made of copolymers of perfluoro( 1,3 -dimethyl-2,2-dioxole) with perfluoro(butenyl vinyl ether) and, optionally, with a third comonmer are amorphous in all monomer proportions, and soluble in perfluoro(2-butyl tetrahydrofuran). Dipolymers of the present invention have lower glass transition temperatures than dipolymers of perfluoro(1,3-dimethyl-2,2-dioxole) with tetrafluoroethylene having the same monomer proportions.
