Abstract The kinetics of the copolymerization of N-isopropylacrylamide (NiPAAm) and diethylene glycol monomethylether monomethacrylate was followed by online 1H NMR spectroscopy. Two copolymerization reactions were sufficient to evaluate the kinetic data with the Extended-Kelen-Tüdös method as well as the nonlinear least square method. The copolymerization parameter was determined as rNiPAAm = 0.70 and rDEGMA = 2.0. The higher reactivity of the methacrylate compared to the NiPAAm is in good agreement with other kinetic data of similar systems.
