BIOACTIVE POLYMERS FOR IMPARTING BIOACTIVE CHARACTER TO HYDROPHOBIC MEDICAL ARTICLE SURFACES

摘要

According to an aspect of the present invention, bioactive polymers are p rovided which have (a) a hydrophilic bioactive portion and (b) at least one hydrophobic polymer group that is linked to the hydrophilic bioactive portio n by a covalent linkage that contains a chain transfer agent residue. Accord ing to another aspect of the present invention, medical articles are provide d with bioactive surface by coating them with a coating material that contai ns such bioactive polymers.
