| 摘要 |
<p>??-????-?-??? PC-009-CIP TITLE POLYCARBONATE HAVING IMPROVED CRITICAL THICKNESS Polycarbonates are provided having improved critical thickness values based on an aromatic diphenol preferably bisphenol A and an aromatic diphenol thioether. By incorporating 2 up to 20 mole percent of the aromatic diphenol thioether based on the total diphenol content into the polymer, the critical thickness of the article molded from the polycarbonate is substantially improved.
