Title:
FIRE RETARDANT POLYCARBONATE AND PREPARATION THEREOF
Document Type and Number:
Japanese Patent JPS52140597
Kind Code:
A
Abstract:
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.
