摘　　要：Nine N,N  diacyl adipic dihydrazides were synthesized. The compounds all exhibited remarkable inhibiting effects on the aging of polypropylene(PP) contacted with copper and their metal deactivation activity was increased with increase in their molecular weight. They didnt reduce the mechanical property of PP. The most effective were N,N  dihexanoyl adipic dihydrazide and N,N  dioctanoyl adipic dihydrazide. At 150 ℃ their aging periods for PP film were over 510 hours.Nine N,N  diacyl adipic dihydrazides were synthesized.
