The poly left bracket (ethylene glycol) dimethacrylates right bracket range from brittle glassy, through rubbery, to semicrystalline network polymers. They and their copolymers provide an ideal medium for establishing structure-property relationships. Preliminary results on two glassy and one rubbery dimethacrylate networks have already been reported. The authors now report on a more extensive study of T//1// rho (H), T//1// rho (C), T//S//L and dynamic mechanical and fracture properties of these and other dimethacrylates. The PE/MAS experiment enables the problem of variable limiting extent of cure to be overcome. This and water content have a very significant effect on both NMR and mechanical dynamic parameters. These studies have been augmented by high power **1H spectrometry. This old technique, particularly when performed using modern equipment, is a valuable adjunct to PE/MAS **1**3C experiments.
