HYDROPHILIC MATERIAL AND ITS PRODUCTION METHOD |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a material having high hydrophilicity and flexibility. <P>SOLUTION: The water-insoluble hydrophilic material is characterized in that it is composed of an inclusion compound constituted of a water-insoluble polyethylene glycol-based polymer and a cyclodextrin-based cyclic compound, and in that the cyclodextrin-based cyclic compound is present within the range of 0.3-30 wt.% against the water-insoluble polyethylene glycol-based polymer. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
