Trifluoroethylene

Trifluoroethylene (abbreviated as TrFE^[3]) is an organofluoride compound with the chemical formula C₂HF₃. It is a colourless gas.^[1] TrFE can polymerise to form poly(trifluoroethylene) (PTrFE). It can also form copolymers with other monomers, such as vinylidene fluoride to form a co-polymer that is used to produce ferroelectric materials.^[4]
