The distribution of sequences in partially hydrolysed polyvinylic alcohol

Abstract The block copolymer structure of partially hydrolysed polyvinyl alcohol was investigated by DSC: This structure was revealed by the dependence of the melting point of crystalline phase against the composition of vinyl alcohol-vinyl acetate copolymers (VOH-VAc) synthesised by different methods. Using the Flory equation, the sequential probabilities p VOH and p VAc representing quantitative values of the sequences distribution along the chain were calculated.
