Synthesis of imide siloxane prepolymers using blocked isocyanates

Bernhard Stapp; Ursula Endres; Gabriele Mösges; Kurt Geibel

Abstract Imide siloxane prepolymers were synthesized from α,ω-anhydride-terminated poly(dimethylsiloxane)s and 4,4′-diphenylmethanediisocyanate. The isocyanate groups were blocked with imidazole or oxime to achieve imide formation by solvent-free condensation at 90°C. The products, which are on average triblock copolymers, were characterized by 1H n.m.r., 13C n.m.r. and i.r. spectroscopy.
