Modified polyacrylate microspheres and preparation method thereof

The invention provides a modified polyacrylate microsphere and a preparation method thereof, the modified polyacrylate microsphere is prepared by mixing activated polyacrylate microspheres with hyperbranched aromatic polyester and galactan solution, and reacting to obtain the modified polyacrylate microsphere. The modified polyacrylate microspheres have good hydrophilicity and excellent mechanical strength. 本发明提供一种改性聚丙烯酸酯微球及其制备方法，所述改性聚丙烯酸酯微球，将活化后的聚丙烯酸酯微球与超支芳香族聚酯、半乳聚糖溶液进行混合，经反应后，得到改性聚丙烯酸酯微球。所述改性聚丙烯酸酯微球具有良好的亲水性，并具有优异的机械强度。
