Abstract
Coatings were prepared from acrylate or methacrylate functionalized resins to study the effect of end group fnctionality on the physical properties of u.v. and electron beam cured coatings. Cure response was measured by solid state NMR and gel extraction, as expected, methacrylate resins cured much slower. Thermal Gravimetric Analysis (TGA) revealed acrylate coatings have greater thermal stability. Properties such as tensile strength and hardness showed little effect of end group functionality or curing method. The O 2 and H 2O permeabilities of the coating were correlated with rhe processing conditions.
