| Abstract: | Polymethylsilsesquioxane was synthesized with methyltrimethoxysilane as a raw material by two-step hydrolysis-condensation.The effects of reaction temperature and pH value on the particle size of the product were investigated.The preferred reaction conditions were as follows:the temperature was 5℃,and the pH value of the system was 4-5.The product was analyzed by infrared spectrum,particle size analysis and micro-morphology,and it was confirmed that the product was silicone resin microsphere,with small particle size,narrow distribution and complete spherical structure. |
