摘要： 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 R
1 represents a hydrogen atom or organic residue, R
2 represents a hydrogen atom, counter ion, or organic residue, and G represents a saccharic residue; where R
1 represents a hydrogen atom or organic residue and R
2 represents a hydrogen atom, a counter ion, or organic residue;

G-H
where G represents a saccharic residue; and

G-R
3
where G represents a saccharic residue and R
3 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.

摘要： A stabilized maleimide compound which is hardly discolored during storage, wherein the content of primary amines is 500 ppm or less, that of maleic anhydride is 5-2,000 ppm, and that of 2-amino-N-substituted succinimide is 300 ppm or less. It is preferable that the content of chlorine compounds be 10 ppm or less in terms of chlorine and that of volatile components having each a boiling point of 200 DEG C or below under an ordinary pressure be 2,000 ppm or less.
