Abstract
An antithrombogenic synthetic polymer has repeat structural units represented by the following structural formula consisting of portions I and II: ##STR1## a microdomain structure composed of crystalline phases and amorphous phases, each phase having an average size of 5 to 10 nm, and a molecular weight in the range of about 10,000 to about 300,000. The polymer exhibits little adhesion of blood platelets thereto, an excellent antithrombogenic property and a sufficient mechanical strength.
