Correlation between hydrogen-bonding self-association and sequence distribution in poly(vinyl acetate-co-vinyl alcohol) copolymers (ACA) with different degrees of basic hydrolysis and sequence distributions has been studied by thermal analysis and NMR spectroscopy. 13 C NMR spectroscopy has also bee
A series of technical composite suspension polymerized poly vinyl chloride products with additions of ethylene-vinyl acetate copolymer (Levapren 450M, 45 wt % VAcl have been investigated with NMR. Partial compatibility is found in these samples, and the phase conditions have been shown to be very mu
