    摘要: 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.

    摘要: Purified bis(3,5-dialkyl-4-hydroxyphenyl) sulfone useful for production of improved carbonate polymer is described. This sulfone is precipitated by deammoniation of an aqueous solution and then removed from the supernatant solution. This produces a product having minimal phenol sulfonic impurities. It may be employed to form carbonate polymer having improved physical properties.
