organosilicon polymers were successfully prepared via step-growth thiol-ene click reaction using mercaptopropylmethyldiallylsilane (AB2) and mercaptopropyltriallylsilane (AB3) as hyperbranched monomers. The structures of the prepared polymers were characterized by Fourier transform infrared spectroscopy and nuclear magnetic resonance spectroscopy. The degree of branching (DB) of the polymers was determined
通过使用巯基丙基甲基二烯丙基硅烷(AB 2)和巯基丙基三烯丙基硅烷(AB 3)作为超支化单体,通过逐步增长的硫醇-烯点击反应成功制备了新型超支化有机硅聚合物。通过傅立叶变换红外光谱和核磁共振光谱对所制备的聚合物的结构进行表征。使用定量29 Si NMR光谱法确定聚合物的支化度(DB)。来自AB 2和AB 3的聚合物的DB分别为0.60和0.22。热重分析的结果表明,硫醚的存在不会影响所得含硅超支化聚合物(Si-HBs)的热稳定性。由于硫醚键,所得的Si-HBs可用作有希望的重金属吸附候选材料。
