Notizen:
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-Tüdős 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.
