Notes:
Hydrogels of biomedical interest were prepared by the free redical copolymerization of 2-hydroxyethylmethacrylate, H, with furfuryl acrylate, A, at low and high conversion. The microstructural analysis of the copolymer system was carried out by nuclear magnetic resonance (NMR) spectroscopy, taking into consideration statistical perameters according to the Mayo-Lewis copolymerization model. The hydration process in physsiological conditions was studied gravimetrically at 37°C, following the kinetics of swelling of homogeneous thin films. A diffusion mechanism based on the stress relaxation model of copolymer chains accounts satisfactorily for the expermental data obtained. The diffusion coefficents determined according to the classical to the Fickian uptake kinetics are very sensitive to the copolymer's composition. © 1994 John Wiley & Sons, Inc.
