Values for the partial molal volumes (~v) of a series of poly(vinyl alcohol-co-vinyl acetate) copolymers, obtained from the same parent poly(vinyl acetate) but of differing degrees of hydrolysis and block size distribution, were obtained from high precision density measurements. An analysis of the d
Near-infrared (NIR) diffuse reflectance spectra have been measured by use of a rotating drawer for pellets of 12 kinds of ethylene/vinyl acetate (EVA) copolymers with vinyl acetate (VA, the comonomer) varying in the 7-44 wt % range. They are unambiguously discriminated from one another by a score pl
Further investigations of the system PVC-EVA, with wide line NMR, have shown that the phase relations differ for graft-polymerized samples and non-grafted samples prepared by milling the polymer components together. The phase relations of the grafted products are not appreciably changed by different
