Aiming at improving the flexibility of polymer films, the copolymers of perfluoro(2-methylene-4-methyl-1,3-
dioxolane) (PFMMD) and chlorotrifluoroethylene (CTFE) with different compositions were prepared by radical
polymerization using perfluorobenzoyl peroxide (PFBP) as the initiator, and their thermal, mechanical, and
optical characteristics were investigated. These copolymers are amorphous, soluble in fluorinated solvents, with
glass transition temperatures (Tgs) in the range of 100–135 °C, and thermally stable to near 400 °C. Stress-strain
curves of polymer films were obtained and tensile strength as well as Young’s modulus were calculated. Film
flexibility and elongation are improved with increasing fraction of CTFE in the copolymers. The copolymer films
have low refractive indices (1.33–1.40) and exhibit extraordinary optical transmittance within the visible and
near-infrared regions. The copolymers are promising materials for applications including plastic optical fibers,
waveguides, and anti-reflective coating.
