Abstract
Bisphenol A polycarbonate containing at least 15 mole % of 2,2-bis-(4-hydroxyphenyl)hexafluoropropane (6F-Bisphenol A) can be blended with polyvinyl chloride (PVC) to form a thermodynamically miscible, transparent, single phase blend at all compositions. Such blends are flame resistant as well as resistant to attack by acids, bases and many organic solvents.
