摘要

用马来酸酐和二乙醇胺采用“两步法”合成了超支化聚酯酰胺，研究了电离辐射对超支化聚合物特性粘数的影响。研究表明，电离辐射对超支化聚合物的特性粘数有影响。不同分子量的聚合物溶液辐照时，有的特性粘数上升，有的下降。而本体辐照时超支化聚合物的特性粘数随吸收剂量增加而下降，并分析了造成特性粘数下降的原因。

Abstract

Hyperbranched polymers from maleic anhydride, diethanolamine and ethylene glycol were syntheized by a two-step method, and radiation effects on intrinsic viscosity of the polymers were studied. The results showed that intrinsic viscosity of all the hyperbranched polymers irradiated in their bulk phase, unlike the irradiated polymers in their solution, decreased obviously, Discussions were made on mechanisms of viscosity decrease.
