| 摘 要： | 采用广角X射线衍射法研究了以聚苯乙烯(PSt)或聚丙烯酸甲酯(PMA)为主链,聚环氧乙烷(PEO)为支链的接枝共聚物及其金属盐络合物的结晶性能。结果表明,在PEO支链分子量相同,且含量相近的情况下,PMA-g-PEO的结晶度(x_0)比PSt-g-PEO小;在金属盐与EO的络合比及其他条件相同的情况下,不同金属盐降低x_0的能力为LiClO_4>KSCN>FeCl_2;接枝共聚物及其金属盐络合物的x_0均随着PEO支链含量的增加而增加。

| Abstract: | Two kinds of graft copolymers , PSt -g -PEO and PMA-g-PEO,were synthesized by the reaction of methacrylate terminated polyethylene macromonomer (PEO-MA) with styrene ( St )or methyl acrylate (MA) .The crystallinity of the graft copolymers and thar metallic ions (LiClO4,KSCN and FeCl2) complexes was measured by wide-angle X-ray diffraction (WAXD) ,and the influences of some factors ,such as the structure of main chain, the content of side chain and the kinds of salts used , on the crystallinity were investigated . |
