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。
In this paper, wide-angle X-ray diffraction, dynamic viscoelasticity, transmission electron microscopy and other test methods were studied ClIIR-g-PS copolymer morphology and compatibility. The results showed that the microcrystal of ClIIR-g-PS copolymer could be formed under the condition of low content of PS and stretching conditions. The phase inversion point of the copolymer was between 33% -36% of the PS content, The area decreases with the increase of PS content. Within a certain range of composition, the copolymer has only one glass transition and becomes a two-phase compatible system. The copolymer and blend voxel proved that the copolymer has good two-phase compatibility, and the copolymer has stronger compatibilization effect on the blend system.
