Thermosensitive Block Copolymers Consisting of Poly(N-isopropylacrylamide) and Star Shape Oligo(ethylene oxide)
Bulletin of the Korean Chemical Society (Print)
Thermosensitive block copolymers of ethylene oxide and N-isopropylacrylamide (NIPAM) were synthesized. A five armed star shape oligo(ethylene oxide) initiator with a cyclotriphosphazene core was prepared and used for the atom transfer radical polymerization (ATRP) of NIPAM. The lower critical solution temperatures (LCSTs) of the copolymers were 36 to 46 o C, higher than that of PNIPAM (32 o C), depending on their molecular weights. The copolymers were soluble in water below the LCSTs but formeddoi:10.5012/bkcs.2009.30.7.1521 fatcat:j5r34ukv6veijkgbi35trpi3xa
