PROBLEM TO BE SOLVED: To provide a medical supply polymer that has excellent biocompatibility but prevents a coating of it having a sticky surface, and is easy to use.SOLUTION: The present invention provides a medical supply polymer that has excellent biocompatibility but prevents a coating of it having a sticky surface, and is easy to use. The medical supply polymer is obtained by the polymer surface-hydrophilization in which a polymer including a hydrophilic group and having a glass transition temperature of 40°C or more is treated with water and/or water vapor of a temperature equal to or higher than the glass transition temperature of the polymer.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】良好な生体適合性を有しながら塗膜表面のべたつきがなく、使用のしやすい医療用具重合体の提供。【解決手段】親水性基を有し、ガラス転移温度が40℃以上の重合体を該重合体のガラス転移温度以上の水及び/又は水蒸気で処理する重合体の表面親水化処理をすることで得られる、良好な生体適合性を有しながら塗膜表面のべたつきがなく、使用のしやすい医療用具重合体【選択図】なし
