  • Polymer for medical device, medical device material and medical device prepared from the material, and monomer composition for polymer for use in production of medical device
    Patent number: 10391205
    Abstract: To Provide is a polymer having high antithrombogenicity compared to a conventional polymer having a glycerol group and suitable as a medical device material. It is the polymer having a structural unit derived from a glycerol group-containing monomer, and a structural unit derived from an unsaturated monomer having a structure in which an organic group having a structure site having 4 or more carbon atoms continuously bound is bound to an ethylenically unsaturated group; and satisfying a glass-transition temperature of 10° C. or less and/or a glass-transition temperature of ?25° C. or less at a saturated water content.
    Type: Grant
    Filed: November 28, 2016
    Date of Patent: August 27, 2019
    Assignees: National University Corporation Yamagata University, Nippon Shokubai Co., Ltd.
    Inventors: Masaru Tanaka, Naoki Kobayashi, Yoshitomo Nakata, Asuka Sugawara
