A method of preparing poly methylsilsesquioxane-dimethylsiloxane copolymer

摘要

The present invention relates to a process for the preparation of dimethyl siloxane groups uniformly in the form of polymethyl silsesquioxane air dispersion polymer, and more particularly, methyl trialkoxysilane (T-structure) with dimethyl-dichloro-silane (D-structure) to a molar ratio of 2:01 by heating the mixed solution after obtaining the type of the precursor coupled to each other, the two materials TDT type, by using a mixed solvent of THF and toluene sol-by-gel reaction was neutralized with aqueous ammonia, dimethyl siloxane molecule is a method for producing methyl siloxane skeleton uniformly in a manner controlled by the molecular level dispersion of the polymethyl silsesquioxane copolymer.
