The struc-ture and physical mechanical properties of graft copolymer depend on the rate of graft. 接枝共聚物的结构和物理性能与接枝率有关。
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。
