## Abstract A series of polymer hydrogels based on 2โhydroxylethyl methacrylate and styrene were synthesized by bulk polymerization. The kinetic and thermodynamic swelling properties of these hydrogels were studied. The swelling mechanism of the hydrogels followed Fickian behavior. The diffusion co
Abstrac~ Sorption isotherms of water vapour were determined for crosslinked poly-2-hydroxyethyl methacrylate (PHEMA), poly-2-(2'-hydroxyethoxy)ethyl methacrylate (PHEOEMA) and statistical copolymers at 35'. In the case of PHEMA the amount sorbed does not depend on the porosity of structure: sorption
Copolymers were prepared of 2-hydroxyethyl methacrylate, which is strongly hydrophilic, with hydrophobic comonomers having a low glass transition temperature, i.e., ethyl acrylate, n-butyl acrylate, and dodecyl methacrylate. The glass transition temperature, T, (1 Hz), of polymers in the dry state (
