摘要：This invention relates to flame retardants for polyester and polyamide

compositions, and specifically relates to compositions containing (1) about 30 to about 70weight percent of a polyester or a synthetic, aliphatic polyamide or a mixture thereof; (2)about 15 to about 40 weight percent of glass or mineral reinforcing agent; and (3) aflame retardant of (a) about 20 to about 30 weight percent of melamine phosphate andup to about 10 weight percent of a charring catalyst; (b) about 15 to about 30 weightpercent of melamine phosphate, up to about 10 weight percent of a charring catalyst andup to about 10 weight percent of a char former; (c) about 5 to about 45 weight percentof melamine pyrophosphate; (d) about 15 to about 30 weight percent of melaminepyrophosphate and up to about 10 weight percent of a charring catalyst; (e) about 15 toabout 30 weight percent of melamine pyrophosphate, up to about 10 weight percent of acharring catalyst and up to about 10 weight percent of a char former, or (f) about 20 toabout 30 weight percent melamine pyrophosphate and up to about 10 weight percent ofat least one of melamine cyanurate, melamine, or zinc borate, wherein all percents byweight are based on the total weight of (1)+(2)+(3) only.
