Synthesis of poly[1,1,1,3,3,3-hexafluoro-2-(pentafluorophenyl)propan-2-yl methacrylate]:Thermal and optical properties of the copolymers with methyl methacrylate

摘要

Poly[1,1,1,3,3,3-hexafluoro-2-(pentafluorophenyl)propan-2-yl methacrylate (I)] was synthesized,and the copolymers of the monomer I with various compositions of methyl methacrylate (MMA) were prepared and characterized.The glass transition temperature values obtained for the copolymers were between 120 and 150 °C.The refractive indices of the copolymers were in the range of 1.4350-1.4872 at 532 nm.They were thermally stable (up to 297-323 °C),and their water absorptive properties were greatly decreased,compared with pure PMMA.
