【Abstract】 The property and structure of six kinds of ACR processing aid (home-madeⅠ,Ⅱ,Ⅲ and Ⅳ, and foreign Paraloid K-125 and Paraloid K-175) were studied by means of GPC, TEM, TG and mechanical skills. The results showed that several defects such as lower molecular mass and excessive compatibility made Ⅰ,Ⅱ,Ⅲ and Ⅳ inferior to Paraloid K-125 and Paraloid K-175, and the four products were indistinctive.更多还原
