✦ Synopsis
Condensation of sodium cyanatc with haloalkyl(meth)acrybttes under sppropriete phase @an&r catalytic conditions led to the setective fernration of monomers containing isqauate. u&am&, urea of isccyanurate group.
The selectivity of these new syntheses of such derivatives depends on the tempexature and the water content of the re4kxion medium.
(Meth)acrylic esters are interesting derivatives in the synthesis of polymeric materials as well as sought as reagents in fine chemistry through their very reactive unsaturation. 1 On the other hand, carbamates, ureas, isocyanates and isocyanurates play an important part in phyto,2medicinal3 and polymer chemistry.4 Thus, it is not surprising that the synthesis of compounds comprising one of these functional group with (meth)acrylic esters continue to be of curtent interest.5
As part of our program6 to develop new chemoselective reactions in the (meth)acrylic series, we were interested in the synthesis of such derivatives.

The two new functional monomers, UMAI and UDMAI, having amide groups were prepared on reaction of methacryloyl isocyanate (MAI) with urea at low temperature. The monomers thus obtained were characterized by elemental analysis, as well as infrared, ultraviolet, 1 H and 13 C-NMR (nuclear magnetic reso
