摘要
对甲醇溶液中甲基丙烯酸缩水甘油脂在羊毛纤维上的γ射线辐射接枝反应作了系统研究。考察了气氛、剂量、剂量率、单体浓度等实验条件对接枝反应的影响,发现气氛对接技反应的影响很小,而接枝率随辐照剂量和单体浓度的增大而提高,接枝效率则随单体浓度的增大而减小。在剂量大于11kGy后接枝率达到平稳状态。用红外吸收谱仪(IR)和扫描电镜(SEM)分析发现单体均匀地接枝在羊毛上。
A systematic study was done on radiation graft-copolymerization of wool samples irradiated by y-rays with methanol solution of methacrylic acid glycidyl ester monomer. It was found that reaction atmosphere did not cause great effects to the graft-copolymerization reaction. The graft rate increased with increasing dose, reaching a status of equilibrium at 11kGy. With increasing monomer concentrations, the graft rate increased, too, whereas the graft efficiency decreased. Results of IR and SEM characterizations of the grafted samples showed that monomer had been grafted uniformly onto the wool fibers.
