| Abstract: | Poly(phenylsilsesquioxane) containing tributylstannyl groups (TBPSQ) was a useful intermediate for the synthesis of organofunctionalized polysilsesquioxane ( 2 ). The reaction of TBPSQ and monochlorosilane ( 1 ), which possessed an organofunctional group, proceeded under mild and neutral conditions to give 2 with the elimination of tributylstannylchloride. The combined use of the different chlorosilanes 1 enabled the ready preparation of multifunctionalized polysilsesquioxanes 2 . The number‐average molecular weights and dispersions of 2 were almost the same as those of starting TBPSQ. © 2001 John Wiley & Sons, Inc. J Polym Sci Part A: Polym Chem 40: 286–292, 2002 |
