| Description | Crosslinked polyimide-poly(dimethylsiloxane)s with theor. content of the siloxane phase up to 60 wt% were prepd. The starting materials were p-aminophenyltrimethoxysilane terminated polyamic acids with no. av. mol. wt. of 10,000 g mol-1, based on 4,4'-oxydiphthalic anhydride and 4,4'-oxydianiline and dimethoxydimethylsilane. The structure of the prepd. polymeric materials was analyzed using 29Si and 13C NMR solid-state spectroscopy. Their thermal and mech. properties, chem. resistance and d. were evaluated. The influence of the basic catalysts employed (ammonium hydroxide) on the course of the reaction and properties of the materials was also studied. |
