ABSTRACT:
Perfluoro-1,3-dioxole is a useful monomer, which polymerizes to either amorphous or liquid homopolymers and copolymerizes with tetrafluoroethylene as well as with other monomers to both crystalline and amorphous copolymers having one or more such comonomers incorporated therein. Amorphous homopolymers and copolymers of perfluoro-1,3-dioxole are useful in such applications as glazing for reactors for hydrogen fluoride reactions. Amorphous homopolymers and amorphous or crystalline copolymers form self-supporting films and can be used for coatings and linings which are inert to most chemicals and are stain and weather resistant and as dielectrics for electrical and electronic equipment. Liquid homopolymers can be used as hydraulic fluids and heat exchange media.
