    摘要: A process for the preparation of ethylenically unsaturated isocyanates is described, which process comprises silylating an appropriate ethylenically unsaturated urethane precursor at the urethane nitrogen and converting the resulting unsaturated N-silyl-urethane by means of thermolysis at elevated temperature into the desired isocyanate. The unsaturated isocyanates obtainable according to the process are suitable, for example, as monomers or comonomers in the preparation of polymerisates or copolymerisates.
