| 摘 要： | 不同摩尔配比（１００／０、８０／２０、５０／５０、２０／８０、０／１００）的十一烯酸乙酯，乙烯基咔唑与含氢聚硅氧烷通过硅氢加成反应进行了接枝。用透射电镜观察了该类聚合物的相结构，当两接枝单体配比相差较大时，含量小的一相为分散相，含量多的一相为连续相；当两者的配比相近时，两相均为连续相。用扭辨仪测其玻璃化转变温度Ｔｇ，该类聚合物的Ｔｇ随乙烯基咔唑含量的增加而增大。但由于乙烯咔唑反应不完全，纯乙烯基咔

| Abstract: | Polysiloxane grafted by ethyl undecylenate and vinyl carbazole were synthesized by Si-H additional reaction. Phase morphology of these grafted polymers were observed by TEM. When the composition of two grafted monomers is 80/20 or 20/80, two phases coexiste, one phase in which the component is rich is continuouse, the other one is disperse. When the mole ratio is 50/50, two phases are both continuouse. Glass transition temperature( T g) of these grafted polymers were measured by TBA. T g of polysiloxane grafted by ethyl undecylenate and vinyl carbazole increase with an increase of content of vinyl carbazole. T g of polysiloxane grafted by vinyl carbazole is the same as that of polysiloxane grafted by ethyl undecylenate because the graft reaction of polysiloxane and vinyl carbazole is not complete. |
