Length effect of methoxy poly(ethylene oxide)-b-[poly(ε-caprolactone)-g-poly(methacrylic acid)] copolymers on cisplatin delivery.

Novel comb-shaped amphiphilic copolymers based on methoxy poly(ethylene glycol)-b-[poly(ε-caprolactone)-g-poly(methacrylic acid)] (MPCL-g-pMAA), were synthesized via ring opening polymerization (ROP) and atom transfer radical polymerization (ATRP) for drug delivery systems. MPCL-g-pMAAs with various MAA repeating units self-assemble into a core-shell structure in an aqueous solution. Critical aggregation concentrations range within 5.6×10
