| 摘 要： | 热力学的理论计算结果以及采用相差显微镜、透射电镜、小角X-射线散射和应力-应变行为等测试方法获得的结果均表明,聚氧化乙烯(PEO)和聚丙烯酰胺(PAM)共混体系相容性差,在高速搅拌下生成的PEO-PAM嵌段共聚物是有效的增容剂,可使PEO/PAM共混体系的微区尺度减小,不均匀程度降低,相区边界层厚度增大,宏观断裂强度增高。

| Abstract: | The compatibility of poly ( ethylene oxide) (PEO)/Polyacrylamide(PAM) system and the compatibilizing effect of PEO-PAMblock copolymcr formed during highspeed stirring of PEO/PAMmixture in its aqueous solution were studied. As viewed from thermodynamics, PEO/PAMis incompatible; the same is true of the conclusions drawn from contrast microscopy, TEM, SAXSand stress-strain behavior testing. It is found, however, that PEO-PAMblock copolymer is an effective compati-bilizer, which could cut down the dimension of the domains, reduce the heterogeneity of the system, increase the thickness of transition layer and improve the mechanical properties of the polyblend. |
