Abstract

Set of new 4,4'-substituted 1,3-diphenoxypropan-2-ol-based methacrylate monomers were designed. Their free radical polymerization provided three homopolymers. These novel polymers were characterized with NMR, IR spectroscopies, as well as DSC and SEC. The effect of substituents in the 4,4-position on the rate of homopolymerization of monomers was investigated and analyzed. It was found, that the highest polymerization rate is observed for monomer with acceptor substituents. For monomer with a donor substituent, the lowest polymerization rate was observed. Glass transition temperature decreased in a row: unsubstituted > acceptor substituent > donor substituent.

摘要

设计了一组新的 4,4'-取代的 1,3-二苯氧基丙-2-醇基甲基丙烯酸酯单体。它们的自由基聚合提供了三种均聚物。这些新型聚合物用 NMR、IR 光谱以及 DSC 和 SEC 进行了表征。研究和分析了 4,4-位取代基对单体均聚速率的影响。发现，对于具有受体取代基的单体观察到最高聚合速率。对于具有供体取代基的单体，观察到最低的聚合速率。玻璃化转变温度连续下降：未取代>受体取代基>供体取代基。
