ABSTRACT:
Epoxy resins which have silicon-containing functional groups along the polymer backbone are prepared by reacting a polyether having non-terminal hydroxy groups with a modifying agent which (i) reacts with hydroxy groups and (ii) which also contains trialkoxysilane groups. The modified resins can be reacted with a silicon oxide precursor to form an organic/inorganic composite. The composites are shown to have improved properties at elevated temperatures.
