| 摘 要： | 采用半连续乳液聚合法，将八硝苯基笼型倍半硅氧烷（ONPS）掺入（甲基）丙烯酸酯乳液中，对其进行改性。透射电镜照片、粒径分布分析、DSC、拉伸强度的测量结果表明：ONPS的加入量低于3％时，明显提高了丙烯酸酯树脂的Tg，同时乳液涂膜的拉伸强度大幅上升，而断裂伸长率略有下降。

| Abstract: | The octa(nitrophenyl)silsesquioxane(ONPS)-modified acrylate emulsion is synthesized by a semi-continuous polymerization in this paper.Analysis by TEM and the particle size distribution show that the ONPS particles are homogeneously dispersed in the emulsion at a nanometer scale.Differential scanning calorimetry test shows that the addition of ONPS increases T_g of acrylate emulsion significantly,as well as the tensile strength of films,but decreases rupture elongation slightly. |
