ClⅡR/PS接枝共聚物研究——Ⅳ.形态及相容性

STUDY ON C11IR/PS CRAFT COPOLYMER Ⅳ. MORPHOLOGY AND M1SCIBILITY

本文应用广角X衍射,动态粘弹仪,透射电镜等测试方法研究了ClIIR-g-PS共聚物的形态和相容性。结果表明,ClIIR-g-PS共聚物在PS含量较低及拉伸条件下,可生成微晶,共聚物的两相相逆转变点在PS含量为33％—36％,共聚物的两相区随PS组分增加而减小;在一定组成范围内,共聚物只有一个玻璃化转变,成为两相相容体系。对共聚物及共混物体素研究证明,共聚物具有较好的两相相容性,共聚物对共混体系有较强的增容作用。

The morphology and miscibility of CⅢR-g-PS copolymer were studied by X-ray, dynamic yiscoelastometer and TEM. The results show that the composition of the graft copolymer at the phase transition point contains around 33%-36% PS and only one T, is observed there under certain conditions. It is concluded, therefor, that the compatibility of the CⅢR/PS blend can be improved by CⅢR-g-PS copolymer.
