Differences in surface chemical composition were found when examining poly (vinylacetateco-vinylalcohol) (PVOH) film surfaces. The content of the acetate groups increased at the outermost surface when dried in air and similar content, when dried against a glass surface, compared to the bulk content.
A study was made of the changes in density, thermal resistance and mechanical and dielectric properties of a number of epoxy polymers cured at high hydrostatic pressure. The possibility of controlling characteristics under pressure is shown. The most important is the change in the glass-transition t
