THERMOPLASTIC POLYMER, PROCESS FOR PRODUCING THE SAME, AND MOLDED ARTICLE |
摘要 |
A thermoplastic polymer containing glutaric anhydride units of the following general formula (1) and having an absorbance at awavelength of 280 nm of at most 0.5 (the absorbance is a value of the polymer film having a thickness of 100 mu m, measured with a UV-visible spectrophotometer) and a glass transition temperature of not lower than 130 DEG C has high-level colorless transparency and good heat resistance, moldability and dwell stability. <CHEM> wherein R<1> and R<2> are the same or different and each represents a hydrogen atom or an alkyl group having from 1 to 5 carbon atoms. |
