Abstract
Thermoplastic compositions which are a solution of polycarbonate and poly(ethylene terephthalate) resins are described. These solutions are produced by melt admixture of a polycarbonate prepared from bis(3,5,dimethyl-4-hydroxy phenyl) sulfone and 2,2-bis(4-hydroxy-phenyl) propane and polyethylene terephthalate) to provide the composition with a single glass transition point.
