Outline of Final Research Achievements

Basic research was conducted to fabricate highly functionalized materials based on organic ester derivatives of cellulose via microscopic incorporation with other polymeric ingredients. Miscible blends exhibiting homogeneity on a nanometer scale were obtained in binary systems of cellulose acetate or propionate with vinyl polymers (N-vinyl pyrrolidone-containing vinyl copolymer and poly(vinyl alcohol)). Compatibilization of an immiscible polymer pair of cellulose acetate (cellulose diacetate or triacetate)/poly(vinyl alcohol) was successfully achieved by adding poly(N-vinyl pyrrolidone) homopolymer as the third polymer component.
