己二酰二肼脂肪族双酰基衍生物的金属减活作用
摘要:
在已研究和开发的酰肼类金属减活剂(MD)中,-NHNH-的封端为芳环者相对较多,而长链脂肪族双酰肼类相对较少[1,2].N,N'-二乙酰基己二酰二肼是Ciba-Geigy公司开发的为聚烯烃所使用的有效金属减活剂[3],考虑到金属减活剂的效率还应与其挥发性、同聚烯烃的相容性等因素有关,我们合成了8种封端碳链更长的己二酰二肼衍生物,并对它们的金属减活性能进行了初步研究.

Aliphatic Diacyl Adipic Dihydrazides for Metal Deactivation
Abstract:
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 dihydra zide. At 150℃ their aging periods for PP film were ov er 510 hours.
