(57) [Summary] (Modified) [Object] To provide an ethylenic compound to which an arginine derivative is bonded, which is useful as a raw material for an antithrombotic polymer material, and a method for producing the same. A compound of general formula I, for example formula IX, and an arginine derivative having a carboxylic acid group having antithrombin activity in the presence of a dehydration condensing agent are esterified with an ethylenic compound having a hydroxyl group such as hydroxyethyl methacrylate. A process for the preparation of this compound. |
