INTERFACIAL PROCESS FOR PRODUCING POLY(ESTER-CARBONATE) CONTAINING PHENOLPHTHALEIN |
摘要 |
An interfacial process for producing a poly(ester-carbonate) containing aromatic dihydroxy moieties derived from phenolphthalein. In the process, phenolphthalein polyester oligomers are formed first, and then the oligomers are reacted with phosgene and with additional aromatic or cycloaliphatic diacyl halide and with an aqueous solution of bisphenol-derived salt to form the poly(ester-carbonate). |
