摘要

研究了在空气条件下丙烯腈和丙烯酸在预辐照聚丙烯无纺布上的共接枝反应，以及预辐照吸收剂量、接枝反应温度、反应时间、单体浓度及比例和摩尔盐浓度对接枝率的影响。结果表明，接枝的最佳条件为：反应温度75℃，反应时间4h，单体浓度50%。并对接枝前后的聚合物进行了红外光谱分析。

Abstract

In this paper, co−grafting reaction of acrylonitrile and acrycylic acid onto pre−irradiated polypropylene nonwoven fabrics in air medium has been studied. The degree of grafting has been determined as a function of irradiation dose, reaction temperature ,reaction time, monomer concentration, ratio of monomers and the concentration of Mohr’s. The results showed that the best condition of grafting reaction was reaction temperature 75℃, reaction time 4h, monomer concentration 50%. Structure of the grafted polymer have been studied by FT−IR.
