FIRE RETARDANT POLYCARBONATE AND PREPARATION THEREOF |
摘要 |
<p>Polycarbonates are provided having improved critical thickness values based on an aromatic diphenol, a halogenated dihydric phenol and an aromatic diphenol thioether. By incorporating an effective amount of the aromatic thiodiphenol based on the total diphenol content into the polymer the critical thickness and flame retardant characteristics of the polycarbonate is substantially improved.</p> |
