Notes:
Selective graft copolymerizations onto different segments of a poly(ether-urethane) (PEU) by using two different methods, i.e. ceric salt initiation and controlled oxidation, were investigated. By ceric salt initiation the grafting takes place mainly at the hard segment, while the controlled oxidation gives grafted hydrogels at the soft segment. The effects of different factors on graft copolymerization in both methods including ceric salt concentration, monomer concentration, PEU composition and oxidation time were investigated. Another kind of multiphase block copolymers, a poly(ether-ester), also can be graft-copolymerized by both methods.
