Abstract:

First;the macromolecule of vinyl-terminated urethane-acrylate was prepared by using toluene diisocyanate（TDI）;polyether polyol（N210;220）and 2-hydroxypropyl acrylate as the monomers;then the urethane-acrylate copolymer was synthesized via frontal free-radical polymerization.The effect of the initiator concentration on the speed and temperature profile of frontal polymerization was investigated.The experimental results showed that FTIR absorption peak of the products synthesized by frontal polymerization(FP)and by batch polymerization(BP) was similar;the thermal stability of the product synthesized by FP was better than that synthesized by BP.
