An acrylic ester derivative expressed by Formula (1) below is produced by reacting an acrylic ester expressed by Formula (2) below with a saccharide containing a hemiacetal hydroxyl group expressed by Formula (3) below and/or an alkylglycoside expressed by Formula (4) below:
where R1 represents a hydrogen atom or organic residue, R2 represents a hydrogen atom, counter ion, or organic residue, and G represents a saccharic residue;
where R1 represents a hydrogen atom or organic residue and R2 represents a hydrogen atom, a counter ion, or organic residue;
G-H (3)
where G represents a saccharic residue; and
G-R3 (4)
where G represents a saccharic residue and R3 represents an organic residue. An acrylic-ester-based polymer is produced by letting a monomeric component containing such an acrylic ester derivative undergo polymerization. The resulting acrylic-ester-based polymer renders excellent hydrophilic property, biodegrability, and bioadaptability, and therefore, can be preferably used as a surface finishing agent, a medical material, a water absorptive resin, a surfactant, etc.
由下式(1)表示的丙烯酸酯衍生物是通过由下式(2)表示的丙烯酸酯与含有由下式(3)表示的半缩醛羟基的糖和/或由下式(4)表示的烷基糖苷反应制得的:
其中 R1 代表氢原子或有机残基,R2 代表氢原子、反离子或有机残基,G 代表糖残基;
其中 R1 代表氢原子或有机残基,R2 代表氢原子、对位离子或有机残基;
G-H (3)
其中 G 代表糖残基;以及
G-R3 (4)
其中 G 代表糖残基,R3 代表有机残基。让含有这种丙烯酸酯衍生物的单体成分发生聚合反应,可生产出丙烯酸酯基聚合物。由此产生的丙烯酸酯基聚合物具有优异的亲水性、生物可降解性和生物适应性,因此可优先用作表面处理剂、医用材料、吸水性树脂、表面活性剂等。
