| 摘 要： | 由甲苯二异氰酸酯（TDI）、聚醚二元醇（N210、220）、丙烯酸-2-羟丙酯（HPA）制得端烯基聚氨酯-丙烯酸酯大分子;然后通过前端自由基聚合;制备了聚氨酯-丙烯酸酯共聚物。研究了引发剂浓度对前端速度和温度分布的影响。FTIR显示前端聚合产物与间歇聚合产物有相似的红外吸收;TGA分析表明;前端聚合产物具有更好的热稳定性。

| 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. |
