PROBLEM TO BE SOLVED: To achieve biocompatibility aiming at highly safe medical and pharmaceutical applications, having effects of suppressing adhesion of biological tissue and cells, suppression of platelet adhesion / activation, and activation of complement system A sex copolymer is provided. SOLUTION: The copolymer is an ethylene oxide copolymer having a side chain represented by the following general formula (1), and has a polyethylene glycol (PEG) equivalent weight average molecular weight of 500 to 500,000. An ethylene oxide copolymer. [Chemical 1] (In the formula, x and y each represent an integer of 1 or more, and y / (x + y) = 0.001 to 0.500. R is hydrogen or a compound residue consisting of 1 to 12 carbon atoms. .) [Selection figure] None |
