Improvement of poly(ester-urethane) surface properties by RAFT mediated grafting initiated by gamma radiation

RAFT (ang. Reversible Addition–Fragmentation chain Transfer) polymerization has been considered as one of the most successful techniques for the preparation of polymers with predetermined molecular weights, narrow molecular weight distributions and high degree of chain end functionalities. This method was used for grafting of N-isopropylacrylamide onto polyurethane (PUR) surface to improve biocompability of the matrix surface. The pristine and...
