The thermal properties have been examined by differential scanning calorimetry and thermogravimetric analysis. The glass transition and the thermal degradation temperatures of glycopolymers increase as hydrophilic component decreases. In addition, the solution properties of the water‐soluble glycopolymers have been investigated, observing the formation of small micelles. Finally, the potential of these
统计的糖基葡糖内酯是通过经典的自由基聚合制备的,然后用1 H NMR原位合成。已经定性地研究了该系统根据整体速率常数的动力学行为。还分析了累积进料和共聚物组成随转化率的变化,显示随着反应的进行两者均减小。单体反应率已使用Mayo-Lewis末端模型和扩展的Kelen-Tüdös方程估算,即r HEMAG = 1.41±0.06和r MA= 0.42±0.05。通过差示扫描量热法和热重分析法检查了热性能。糖类聚合物的玻璃化转变温度和热降解温度随着亲水性成分的降低而增加。此外,还研究了水溶性糖聚合物的溶液性质,观察到了小胶束的形成。最后,通过丙烯酸甲酯的乳液聚合性能证明了这些糖聚合物作为聚合物表面活性剂的潜力。所得颗粒是稳定的并且具有低多分散性,随着糖聚合物表面活性剂中丙烯酸甲酯含量的增加,粒径减小。©2010 Wiley Periodicals,Inc.
