CHLOROBROMINATED DICARBOXYLIC ACIDS, PROCESS FOR THEIR PREPARATION AND THEIR USE IN MAKING SYNTHETIC MATERIALS FLAME-RESISTANT

摘要

The invention relates to diacids resulting from tetrahydrophthalic acid (chlorendic acid). The diacids correspond to the formula in which R represents the radical or the radical They are prepared using an excess of chlorendic acid. They can be used as fireproofing additives for polymeric materials or as prepolymers for polycondensation reactions.
