uv curing setup showed that cardanol remained as a liquid without much curing happening whereas the modified cardanol appeared like a transparent film though still tacky in a very short time the curing kinetics could be followed by the disappearance of the peaks of unsaturation using an ftir spectrometer in cardanol the peak intensity did not vary much fig2 whereas in the telechelic urethane methacrylates of cardanol as well as derivatives of cardanol the intensity of the above mentioned unsaturation peaks reduced drastically cardanol and its derivatives are known for their anti oxidant properties as discussed in j chem soc perkin trans 2 2001 2142 2146 by amorati r et al which explains the difficulty in its photoinduced curing process in the urethane meth acrylate pre polymers v in addition to the unsaturation in the side chain there is a polymerizable meth acryloyloxy group which also can undergo curing in presence of photoinitiators complete disappearance of the methacrylic double bond as observed in their ftir spectra leads to the formation of a transparent film of the cross linked material fig3 4 gives the ftir spectra of the telechelic urethane methacrylates of cardanol as well as derivatives of cardanol with the peak positions labeled according to the present invention the uv curable telechelic urethane methacrylic resin are synthesized from the renewable resource cardanol as well as the derivatives of cardanol according to another aspect of the present invention uv curing of the above mentioned resins were carried out in the presence of.
