Anionische polymerisation von ω-isocyanatocarbonsäuretrialkylsilylestern

ω-Isocyanatopropionic and -butyric acid trialkylsilyl esters are converted to polyisocyanates by means of anionic polymerisation. Polymeranalogous reactions (hydrolysis, transesterification) of the silyl ester groups are possible though being limited by the occurrence of depolymerisation at elevated temperatures.
