Polyamide resins flame retarded by poly(metal phosphinate)s

摘要

Polyesters, polyamides and polyester-polyamides are flame retarded by incorporating a flame retardant amount of selected poly(metal phosphinate) s with the resins. The poly(metal phosphinates)s can be incorporated with the resins either by admixture of the poly(metal phosphinate)s with the polyester or polyamide or by adding the poly(metal phosphinate)s to the polyester or polyamide polymerization reaction whereby the poly(metal phosphinate)s become a part of the polymer structure.
