Polyether modified polysiloxane defoaming agents which was prepared by using hydrogenous polysiloxane and polyether as startintg materials, has good properties. 在聚硅氧烷链段上引入聚醚链段而得到的聚醚改性聚硅氧烷消泡剂是一种性能优良的消泡剂。
It was shown that the modified membranes with higher grafting rate expressed better anti-fouling ability in the ultrafiltration of protein solutions. 实验结果表明，随着接枝率的提高，改性聚砜膜抗蛋白质吸附污染的能力显著增强。
