N-Methyl bis[(nonafluorobutane)sulfonyl]imide (Nf2NMe) was synthesized to serve as an initiator for polymerization of 2-oxazolines and the polymerization activity and control of molecular weight were compared with conventional methyl triflate (TfOMe). Ring-opening polymerization of the vinyl-containing 2-oxazoline, 2-(3-butenyl)-2-oxazoline, and a subsequent thiol–ene click reaction and oxidation resulted in the successful synthesis of electrophoretic poly(2-oxazoline)s containing pendent sulfone. It was possible to coat the polymeric sulfones obtained via oxone oxidation (conversion, >99%) on a stainless-steel anode selectively. Furthermore, hybridization of the poly(2-oxazoline)s with bioactive glass (Bioglass45S5) by electrophoretic deposition (EPD) was investigated, and the biocompatibility of the hybrid was also evaluated.
合成了N-甲基双[(九氟丁烷)磺酰基]亚胺(Nf2NMe)作为2-恶唑啉聚合的引发剂,并与传统的三氟甲磺酸甲酯(TfOMe)进行了聚合活性和分子量控制的比较。含乙烯基的2-恶唑啉、2-(3-丁烯基)-2-恶唑啉的开环聚合,以及随后的硫醇-烯点击反应和氧化,成功合成了含有悬挂的砜。可以将通过过氧化氢氧化(转化率>99%)获得的聚合砜选择性地涂覆在不锈钢阳极上。此外,通过电泳沉积(EPD)研究了聚(2-恶唑啉)与生物活性玻璃(Bioglass45S5)的杂交,并评估了混合物的生物相容性。
