H-1- and C-13-NMR techniques were used to study the microscopic struct
ure of NMA/VP copolymer hydrogels. Evidence was obtained for a plastic
ization effect of MMA chains by VP. An original H-1-NMR approach revea
led the existence of several types of water with various degree of bou
nding to the polymer network, a conclusion that is corroborated by a c
omplementary C-13-NMR study. (C) 1997 John Wiley & Sons, Inc.
