摘要：

A new class of polyhedral oligosilsesquioxane (POSS) copolymers has been developed by incorporating into a polymer backbone the POSS disilanol macromer, (c-C6H11)(8)Si8O11(OH)(2), along with a variety of inorganic comonomers. These new inorganic cluster-based copolymers were synthesized using a condensation polymerization approach, with formation of metal-oxygen bonds and elimination of HCl (as RNEt(3)Cl) or CH4 driving the reaction. The polymers thus formed are isolated as amorphous powders but do not display any observable glass transition; they decompose without melting at over 400 degrees C under nitrogen. Especially interesting is the formation of a zirconocene-bridged copolymer which is stable to both air and methanol.
