In this work we focused on synthesis and characterization of aqueous poly(N-vinylcaprolactam) (PVCL) microgels decorated with oligoglycidol-macromonomers. Oligoglycidol macromonomers with styrene or acrylate polymerisable group and tunable length of the oligoglycidol chain (6, 12 and 50 glycidol units) were synthesized. The microgels were synthesized by aqueous precipitation copolymerization of N-vinylcaprolactam and oligoglycidol macromonomers in presence of crosslinking agent. The length of the oligoglycidol chain and the concentration of macromonomer in the reaction mixture were varied to investigate a direct influence on the polymerization rate and microgel properties. Synthesized microgels exhibit radii from 50 to 350 nm and show temperature-responsive properties. We demonstrate that oligoglycidol macromonomers are localized predominantly on the microgel surface. This ensures excellent colloidal stabilisation of oligoglycidol-decorated microgels in aqueous solutions and functionalization of microgels with hydroxyl groups, which can be potentially used for further post-modification reactions.

在这项工作中，我们专注于用低聚缩水甘油-大分子单体修饰的聚（N-乙烯基己内酰胺）（PVCL）水性微凝胶的合成和表征。合成了具有苯乙烯或丙烯酸酯可聚合基团和可调节长度的低聚缩水甘油链的缩水甘油大分子单体（6、12和50个缩水甘油单元）。通过N的水相沉淀共聚合成微凝胶。-乙烯基己内酰胺和低聚缩水甘油大单体在交联剂的存在下。改变缩水甘油糖链的长度和反应混合物中大分子单体的浓度，以研究对聚合速率和微凝胶性质的直接影响。合成的微凝胶的半径为50至350 nm，并具有温度响应特性。我们证明了低聚缩水甘油大分子单体主要定位在微凝胶表面上。这确保了低聚缩水甘油修饰的微凝胶在水溶液中的出色的胶体稳定性以及带有羟基的微凝胶的功能化，这可潜在地用于进一步的修饰后反应。
