摘要

Heat stabilized synthetic polyamide compositions are prepared by incorporating therein a mixture of a phenolic antioxidant and metal hypophosphite. A typical embodiment includes polyamides which are stabilized with 1,2-bis[3-(3,5-di-t-butyl-4-hydroxyphenyl)propionamido]ethane and sodium hypophosphite.
