Condensation of sodium cyanate with haloalkyl(meth)acrylates under appropriate phase transfer catalytic conditions led to the selective formation of monomers containing isocyanate, carbamate, urea or isocyanurate group. The selectivity of these new syntheses of such derivatives depends on the temperature and the water content of the reaction medium.
