Abstract
Polyimide-siloxane with reactive functionalities in siloxane segment were synthesized and their properties were investigated. The vinyl-containing polyimide-siloxane was derived from 3, 3', 4, 4'-benzophenonetetracarboxylic dianhydride /bis[4-(3-aminophenoxy)phenyl] sulfone combined with vinyl-containing diamino(poly)siloxane and imidized by solution method. The vinyl groups of the polyimide were reacted easily with various hydrosilanes to form the corresponding crosslinked polyimide. Further silicate-containing polyimide was synthesized by hydrosilation of the vinyl-containing polyimide-siloxane and the alcohoxysilane. The silicate-containing polyimide-siloxane were easily hydrolyzed to give crosslinked polyimide during the process of preparing their films by curing. These crosslinking reaction in both of functionalized polyimides were taken place between siloxane chain which is soft segment. As the results, thermal and mechanical properties of the crosslinked polyimide-siloxane were largely enhanced compared to non-crosslinked polyimide.
