Polyvinyl Alcohol Melt Processing
Source abstract
Abstract
The melt processing behavior of polyvinyl alcohol (PVOH) acquired by polyvinyl acetate solution and suspension hydrolysis is studied. It is found that the PVOH obtained by suspension hydrolysis is much more suitable for melt processing because of the shape and size of the particles and of the chemical and morphological homogeneity. These advantages increase the practical importance of the suspension hydrolysis technology as compared to the solution.
