METHOD FOR REDUCING ODOR DURING PROCESSING OF FLAME RETARDANT POLYMERS

摘要

A method for reducing the odor formed during thermal processing of a thermoplastic polymer composition containing a tris(trihaloneopentyl) phosphate flame retardant additive is disclosed. The method comprises processing a polymer composition containing the thermoplastic polymer, the flame retardant additive, and a quantity of a hydrotalcite effective to reduce the odor formed during processing at an elevated temperature. The method is especially suited for processing polymers that must be processed above 230 DEG C, such as polypropylene, polybutylene terephthalate, and polycarbonate.
