Description

General description

2,3,4,5,6-Pentafluorostyrene is a fluorinated monomer.

Application

Copolymers of 2,3,4,5,6-Pentafluorostyrene and N-phenylmaleimide were synthesized by free radical polymerization. Diblock copolymers of D,L-lactide and pentafluorostyrene with narrow molecular weight distributions have been reported. Fluorinated and photocrosslinkable liquid prepolymers have been synthesized for flexible optical waveguides, the prepolymers are photocurable to afford flexible and transparent films. Phase copolymers consisting of poly(methylmethacrylate) (p-MMA)/n-butylacrylate (nBA) and poly(nBA)/pentafluorostyrene (p-PFS)have been prepared.
