摘要

本工作采用,60,Co γ射线预辐照方法，研究聚丙烯毡在丙烯酸水溶液中的接枝共聚反应动力学。探讨了预辐照剂量，辐照气氛，接枝反应温度以及单体浓度对接枝共聚反应的影响。实验结果表明接枝反应速率与预辐照剂量的关系为0.445次方。由此得知反应是按自由基机理进行的。此外，计算了本体系的表观活化能为25.52 kcal/mol。由本试验获得的接枝共聚物，其亲水性、透气性、及染色性均有明显地改善。但预辐照剂量超过1×10,6,rad机械强度有所下降。

Abstract

A Kinetic study has been made on the pre-irradition grafting of aqueous acylic acid onto polypropylene nonwoven.,The effects of grafting condition, such as pre-irradiation dose, environment atmosphere, grafting temperature and monomer concentration were investigated.,The dependence of the grafting rate on pre-irradiation dose was found to be 0.445 order. It can be concluded that the grafting copolymerization proceeds via a radical mechanism. The apparent activation energy for the grafting polymerization was calculated to be 25.52 kcal/mol.,The products obtained from this experiment showed that hydrophilicity, gas penetrability and dying ability were improved. But mechanical strengh of products decreased with pre-irradiation dose over 2×10,6, rad compared with origonal sample.
