Polyvinyl alcohol polymer, and method for producing hydrolyzable cellulose using the same

Abstract

A polyvinyl alcohol polymer capable of, in producing hydrolyzable cellulose using a cellulosic biomass as a basic material, readily disrupting the cellulosic biomass at a molecular level by imparting a suitable flow resistance to a solution containing the cellulosic biomass, or the like, thereby resulting in efficient production of hydrolyzable cellulose to be enabled; and a method for producing hydrolyzable cellulose using the polyvinyl alcohol polymer. Provided is a polyvinyl alcohol polymer for use in producing hydrolyzable cellulose using a cellulosic biomass as a basic material, the polyvinyl alcohol polymer having: an average degree of polymerization of no less than 200 and no greater than 5,000; a degree of saponification of no less than 70 mol % and no greater than 99.9 mol %; and a molecular weight distribution of no less than 2.2.
