摘　　要：研究了聚碳酸亚丙酯与丙烯酸甲酯丙烯酸共聚物的混合稀溶液性质，发现在一定条件下两种高分子可以生成氢键复合物。其氢键强度、复合物的稳定性受溶剂类型、体系ｐＨ值、温度、聚合物的组成和分子量的影响。Dilute solution properties of poly(propylene carbonate)(Ⅰ), acrylic acid methyl acrylate copolymer(Ⅱ) and their mixtures were studied. The results conformed the presence of hydrogen bonding in the solution of the mixed polymers through COOH of Ⅱ and CO 3 of Ⅰ. It was found that the formation of complexes was influenced by solvents, blending ratio, concentration and molecular weight of the polymers. In the case of combining a random copolymer Ⅱ containing 33 mass% of AA and the polymer Ⅱ with n lager than 3000, good complexation is obtained when pH=5. DOX/MeOH=4(V/V) and Ⅰ/Ⅱ=0.6(unite mole ratio).
