ABSTRACT:
New biocompatible polymeric systems carrying triflusal or HTB are described which result from the polymerization of a monomer A of the acrylic or vinylic type and carrying triflusal or HTB, wherein triflusal or HTB are linked to the remainder of the molecule of said monomer through an in vivo hydrolysable covalent bond, and optionally a second polymerisable monomer B. These new polymeric systems are useful as coating for synthetic biomaterials.
