Abstract
|
The kinetics of the copolymerization of <I>N</I>-isopropylacrylamide (NiPAAm) and diethylene glycol monomethylether monomethacrylate was followed by online <SUP>1</SUP>H 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 <I>r</I><SUB>NiPAAm</SUB> = 0.70 and <I>r</I><SUB>DEGMA</SUB> = 2.0. The higher reactivity of the methacrylate compared to the NiPAAm is in good agreement with other kinetic data of similar systems. © 2004 Wiley Periodicals, Inc.
