摘要
运用前沿聚合法制备聚双环戊二烯,通过聚合物外貌分析及具有恒定的聚合速率说明发生了纯前沿聚合。当采用水浴加热上行聚合模式,且单体、主催化剂、助催化剂的物质的量之比为1200:1:20时,能够保证双环戊二烯按前沿聚合法生成聚双环戊二烯。随着缓聚剂四氢呋喃的质量分数由0.6%上升到4.8%,前沿聚合速率由4.82mm·min-1下降到0.81mm·min-1,前沿最高温度由132℃下降到74℃。
Polydicyclopentadiene was prepared via frontal polynenzanonvr when only pure appearance of polymer and the hybrids front propagates at a constant velocity, thus it provided the evidence FP occurred. It can be sure that dicyclopentadiene was synthesized polydicyclopentadiene via FP when used water bath heat- ing ascending FP mode and monomer, the main catalyst, cocatalyst ratio of amount of substance was 1200:1:20, As the mass fraction of inhibitor tetrahydrofuran enhanced from 0.6% to 4.8% ,the frontal velocity decreased from 4.82mm · min-1 to 0. 81mm · min-1 and the frontal temperature deereased from 132℃ to 74℃ .
