(57) [Abstract] [Problem] Cell damage caused by dynamic frictional contact with living tissue, To develop a medical material that suppresses damage as much as possible and has excellent gas permeability. The present invention provides a dextran ester copolymer obtained by copolymerizing a dextran ester with a siloxane group-containing polymerizable vinyl compound, a perfluoroalkyl group-containing polymerizable vinyl compound and a polymerizable carboxylic acid. . |
