聚合物和共聚物的基础上的单甲基丙烯酰酯和乙烯基苄基醚的蔗糖，轴承无论是封闭的或自由的羟基基团，在自由基催化剂的存在下合成，其结构和尺寸进行了表征。合成了一系列苯乙烯和O-甲基丙烯酰蔗糖的共聚物。用扩展的Kelen-Tudders法计算了共聚单体的竞聚率。通过比较封闭和未封闭共聚物的玻璃化转变温度，评估了蔗糖部分的羟基对热机械性能的影响。它们的溶解特性也进行了测定，它表明，亲水-疏水性能可以控制的蔗糖甲基丙烯酸酯在共聚物中的量。
Polymers and copolymers based on the monomethacryloyl ester and the vinylbenzyl ether of sucrose, bearing either blocked or free hydroxyl groups, were synthesized in the presence of free-radical catalysts, and their structures and dimensions were characterized. A range of copolymers of styrene and O-methacryloylsucrose was prepared. Reactivity ratios of the comonomers were calculated by the extended Kelen-Tudős method. The influence of the hydroxyl groups of the sucrose moiety on the thermomechanical properties was assessed by comparing the glass transition temperatures of both blocked and unblocked copolymers. Their solubility characteristics were also determined, and it was shown that the hydrophilic-hydrophobic properties can be controlled by the amount of sucrose methacrylate in the copolymer.
