Bis [4- (4-hydroxyphenyl) -phenyl] alkane and polycarbonate produced therefrom |
| abstract |
(57) [Summary] [Objective] To provide a polycarbonate having ductility and a high glass transition temperature. A bis [4- (4-hydroxyphenyl) -phenyl] alkane, such as 2,2-bis [4- (4- Hydroxyphenyl) -phenyl] propane may be prepared by reacting a bisphenol A ester or a similar compound with a p-trialkyltin-substituted anisole and then demethylating with a Lewis acid such as boron tribromide. . The polycarbonate produced therefrom is ductile and has a high glass transition temperature. |
