摘要
用羟基封端的聚二甲基硅氧烷，在偶氮二异丁腈引发剂的作用下，与甲基丙烯酸（酯）类进行溶液共聚。用红外光谱研究了改性树脂的固化过程，发现改性树脂中有机硅链段在固化过程中更富集于表面，而丙烯酸链段却倾向于涂层内，使得改性树脂具有良好的疏水性、耐热性和柔韧性；保持了甲基丙烯酸（酯）树脂的力学性能和固化速度。
The solution condensation of dimethysiloxane rubber and polyacrylate has been synthsized. The curing process, hydrophobicity and heat stability of copolymer was studied using FTIR, DTA, TG. The results show that modified resin has good hydrophobicity, heat stability and mechanics.
