Abstract

A composition for the surface treatment of a polymer material includes a hyperbranched polyglycerol comprising a glycidol-derived repeating unit and an unsubstituted or substituted acrylate group at least at one end thereof. The composition has the effect of suppressing fibrosis, thrombus formation, or inflammatory cell adsorption by preventing proteins from being adsorbed to the surface of a polymer material that is surface-treated with the composition or an in-vivo implantation material including a polymer material.

First claim

treating at least a portion of a surface of the polymer material with the composition according to claim 1 and a crosslinking agent.

14 . The method for surface treatment of a polymer material according to claim 13 , wherein the step of treating is performed by immersing the polymer material in the composition, and then immersing in the crosslinking agent.

15 . The method for surface treatment of a polymer material according to claim 13 , wherein the crosslinking agent is PETMP (pentaerythritol tetra(3-mercaptopropionate), pentaerythritol tetrakis(3-mercaptopropionate)).
