Description
Compared to poly(N-isopropylacrylamide) PNIPAM, poly(N-isopropylmethacrylamide) PNIPMAM shows different behavior, though it has a similar chemical structure, only with additional methyl groups on the backbone, e.g. a higher transition temperature (43 °C instead of 32 °C). We studied the temperature-dependent phase behavior of PNIPMAM in D2O using small-angle neutron scattering. Different from PNIPAM, inhomogeneities and physical crosslinks appear in the one-phase state due to the methyl groups.
