摘　　要：指出了根据PVA与PAA的简单对比得出的PVA比丙烯酸类浆料易生物降解的观点是不科学的。PAA是丙烯酸类浆料中唯一未被纺织厂应用的品种,用PVA与PAA对比,也不能说明丙烯酸类浆料生物降解性的难易,凡丙烯酸类浆料中含丙烯酰胺组分占总单体克分子量17以上者均是易生物降解的。This paper points out the viewpoint that PVA size has better biological degradability than PAA size is unscientific,this viewpoint based on a simple comparision between PVA and PAA size,the writer considers PAA is the only one product that not yet applicated in textile mills,the comparision between PVA and PAA can't indicate the case of biological degradability about acrylic acid size,the biological degradability about acrylic acid size is better when the mole of acrylamide constitutent is more than one\|seventh in total mole.

关 键 词：PVA 丙烯酸类 浆料 生物降解性 酰胺基 克分子量
