| Abstract: | Ladder Polymethylsilsesquioxane (PMS) was synthesized with methylch-lorosilane (MTS) and amine as ladder template. The influence of hydrolytic temperature, solvent, molar ratio of water to MTS, polycondensation temperature, polycondensation time and the structure of amine on the properties of PMS was discussed. The optimal conditions were obtained.The thermogravimetry showed that PMS was possessed of excellent heat weight loss ratio of PMS was 4% at 700 . |
