Abstract

Bisphenol A polycarbonate containing at least 15 mole % of fluorinated bisphenol monomer units such as 2,2-bis-(4-hydroxyphenyl) hexafluoropropane (6F-Bisphenol A) can be blended with polymethyl methacrylate (PMMA) to form thermodynamically miscible, transparent, single phase blends at all compositions.
