Synthesis and characterization of copolymers of perfluoro(2-methylene-4,5-dimethyl-1,3-dioxolane) and perfluoro(2-methylene-1,3-dioxolane).

Highlights: [•] Perfluorinated ideal random copolymers are synthesized and characterized. [•] The copolymers can be amorphous or crystalline depending on the composition. [•] The amorphous copolymers are transparent and soluble in fluorinated solvents. [•] The T gs of the copolymers do not change linearly with the composition. [•] They are thermally stable (>378°C) and have low refractive index (1.32–1.34). [ABSTRACT FROM AUTHOR]
