Abstract Degradable, amphiphilic graft copolymers of poly (ε-caprolactone)-graft-poly (ethylene oxide), PCL-g-PEO, were synthesized via a grafting onto strategy taking advantage of the ketones presented along the backbone of the statistical copolymer poly (ε- caprolactone)-co-(2-oxepane-1, 5-dione),(PCL-co-OPD). Through the formation of stable ketoxime ether linkages, 3 kDa PEO grafts and p-methoxybenzyl side chains were ...
