In this study, a random copolymer of N‐isopropylacrylamide and N‐vinyl‐pyrrolidone [poly(NIPAM‐co‐NVP)] having a thermoresponsive character was prepared by a radiation copolymerization method. Poly(ethylene glycol), PEG 4000, was included in the copolymerization recipe to increase the thermoresponsivity of the resultant copolymeric structures. NIPAM‐co‐NVP copolymers with different thermoresponsive properties were obtained by changing the initial NIPAM/NVP mol ratio, total monomer, and PEG 4000 concentrations. © 1997 John Wiley & Sons, Inc.
