By using non-ionic and multidentate halogen bonding organocatalysts, the cationic polymerization of IBVE was investigated to reveal the relationship between the catalytic activity and the substitution pattern of halogen bond donor units with the aid of theoretical calculation. The polymerization successfully proceeded at room temperature using an appropriate catalyst. The polymerization of other vinyl ethers and styrene derivatives was also investigated in the presence of ionic organocatalysts to figure out that the coordination ability of the counter anion significantly affected the catalytic activity. In particular, the polymerization of pMOS occurred in a controlled manner enabling the molecular weight regulation by ca. Mn = 10 000.

使用具有不同活性的卤素键合有机催化剂进行乙烯基单体的阳离子聚合

通过使用非离子型和多齿型卤素键有机催化剂,通过理论计算,研究了IBVE的阳离子聚合反应,揭示了催化活性与卤素键供体单元的取代方式之间的关系。使用适当的催化剂,在室温下成功进行了聚合。还研究了在离子有机催化剂存在下其他乙烯基醚和苯乙烯衍生物的聚合反应,以发现抗衡阴离子的配位能力显着影响了催化活性。特别地,pMOS的聚合以可控的方式发生,从而使得分子量可以通过约2μm调节锰= 10000
