摘　　要：聚马来酸酐是聚烯烃、氯化聚烯烃用马来酸酐接枝改性的副产物。研究其基础物性对接枝反应产物的使用和分离具有一定的价值。本文测定了聚马来酸酐在 2 8种溶剂中的溶解性能 ,表明该物质能完全溶解在酮类、醇类、醚类、酯类等极性溶剂中 ,而在非极性的脂肪烃、芳烃类溶剂中不溶。用特性黏度法测定了该聚合物的溶解度参数为 2 2 .10 (J·cm-3 ) 1/2 。用共溶剂法研究了聚马来酸酐与其他树脂的相容性 ,发现该聚合物可以和氨基树脂 ,醇酸树脂 ,聚氨酯 ,丙烯酸树脂等完全相容。Polymaleic anhydride was byproduct of maleic anhydride grafted polyolefins or chlorinated polyolefins.The research on its basic properties was useful for application and separation of the grafted-product .The soluble properties of polymaleic anhydride in 28 solvents and intrinsic viscosity in different solvents were determinated. The polymaleic anhydride was soluble in ketones, lower alkyl alcohols, ethers and esters,but was insoluble in apoler aromatic and fatty hydrocarbons. Intrinsic viscosity was used for determining the solubility parameter, the result was 22.10(J/cm 3) 1/2 ?Compatibility of polymaleic anhydride and resins was investigated by means of co-solvent method,the results showed that the polymer and amine resin,alkyd resin,acrylic resin,polyurethane were completely compatible.
