    Preparation and Characterization of Novel Bifunctional Hyperbranched Polymers

    • 摘要: 首先以烯丙基缩水甘油醚与N-氨乙基哌嗪反应合成新型B3单体,然后分别以六亚甲基二异氰酸酯和1,6-己二硫醇为A2单体与上述B3单体反应,利用异氰酸-羟基以及巯基-烯的反应,合成了同时含有羟基和烯丙基的双功能性超支化聚(氨酯-胺)和聚(硫醚-胺)。研究了单体种类及投料比与合成的超支化聚合物的化学与拓扑结构的关系。通过红外吸收光谱、核磁共振氢谱和凝胶渗透色谱表征了超支化聚合物的分子结构和化学组成。结果表明:该B3单体同时带有3个羟基与3个烯丙基,当A2和B3单体投料比(物质的量之比)为0.825:1时,可以成功制备较高分子量的双功能性超支化聚合物。

       

      Abstract: First of all, a new type of B3 monomer bearing three hydroxyl groups and three allyl groups was synthesized from allyl glycidyl ether and N-aminoethyl piperazine. Then, the synthesized B3 monomer could react with A2 monomer, hexamethylene diisocyanate or 1, 6-hexanedithiol, to generate bifunctional hyperbranched poly(urethane amine) or hyperbranched poly(thioether amine) bearing both hydroxyl and allyl groups via isocyanato-hydroxy or thiol-allyl reaction, respectively. The effects of monomers and feeding ratios on chemical and topological structures of the hyperbranched polymers were also studied. Finally, the structure and chemical composition of the hyperbranched polymer were characterized by FT-IR, 1H-NMR, and GPC. Results indicated the successful preparation of B3 monomer and bifunctional hyperbranched polymers with the feed mole ratio of A2 and B3 at 0.825:1.
