采用高效的巯基-炔点击化学与Menschutkin季铵化反应,合成了一种带有1个叠氮基、2个炔基和2个季铵盐基团的AB2型季铵盐单体,通过核磁共振、红外光谱、质谱等方法对单体结构进行了确认.将所得单体进行点击聚合,得到全季铵盐超支化聚合物,并用端叠氮基的长链烷烃封端,得到核亲水-壳憎水的两亲性超支化聚季铵盐.研究所得两亲性超支化聚合物对染料的装载性能,结果表明所合成的带正电荷两亲性聚合物对多种带负电荷的水性染料装载效果好,平均相转移率高达95%.进一步将装载染料的主-客体超分子复合物用于聚合物制品着色,发现其对SBS及PMMA等聚合物有很好的着色效果,着色均匀且不掉色,着色的膜色泽鲜艳透明.
A kind of AB2 quaternary ammonium salt monomer with one azido group, two alkynyl groups and two quaternary ammonium salt groups was synthesized by efficient thiol-alkyne click chemistry and Menschutkin quaternization. Resonance, infrared spectroscopy, mass spectrometry, etc. The monomer structure was confirmed by click polymerizing the obtained monomer to obtain a quaternary ammonium salt hyperbranched polymer, and terminated with azido long-chain paraffins to obtain nuclear hydrophilic --Hydrophilic Amphiphilic Hyperbranched Polyquaternary Ammonium Salt The amphiphilic hyperbranched polymers were tested for their loading properties to dyes and the results showed that the synthesized positively charged amphiphilic polymers exhibited good performance for various negatively charged The aqueous dye loading effect is good, the average phase transfer rate is as high as 95% .Further dye-loaded host-guest supramolecular complexes used in coloration of polymer products and found that the SBS and PMMA polymers have good coloring effect, coloring Uniform and not fade, colored film bright color and transparent.
