摘要
A method of preparing an organotin containing hyperbranched polysiloxane structure includes the following steps: (1) by weight, 0.5-1.5 portions of hyperbranched polysiloxane with reactive functional groups is dissolved in 50-100 portions of an alcohol solvent, to obtain a solution A; (2) by weight, 0.5-0.9 portions of a tin-based initiator and 50-100 portions of the alcohol solvent are mixed to obtain a solution B, wherein said tin-based initiator is selected from dihydroxy butyl tin chloride, butyl tin trichloride, and dibutyl tin dichloride; and (3) dropping the solution B into the solution A at the temperature of 0° C.-60° C., reacting for 3-6 h, filtering and drying to obtain the organotin containing hyperbranched polysiloxane structure.
