摘要：

Various molecular parameters characterizing solution properties of poly (N-isopropylmethacrylamide) (PNiPMAM) (in the range of molecular weight from 13.0 to 252 x 10(4)) in water at 20-degrees-C were obtained by use of static and dynamic light scattering techniques. The molecular weight dependence of these parameters is expressed by the power law relation and compared with those for poly(N-isopropylacrylamide) (PNiPAM) in water. It was found that in aqueous solution PNiPMAM molecules take more expanded structures than PNiPAM molecules due to the presence of methyl group to the alpha-carbon.
