Process for the preparation of aromatic polyesters |
摘要 |
High-molecular polyesters which are distinguished by good processability, a high glass transition temperature, mechanical strength and clear transparency are reproducibly obtained by transesterifying and polycondensing bisphenols with diaryl terephthalates and/or diaryl isophthalates in the presence of an aromatic polycarbonate having a molecular weight of 600 to 15,000.
