Abstract

There is provided a process for producing a medical, material that retains the properties which are inherent in a polyanionic polysaccharide being a raw material, that has a high level of safety because there is no need to use a chemical crosslinking agent, and that has moderate strength and flexibility. The present invention is a process for producing a medical material, the process including a step of dispersing a powder or a granular product of a first polyanionic polysaccharide, the first polyanionic polysaccharide water-insolubilized with a treatment liquid containing a first acid anhydride, in an aqueous solution of a water-soluble salt of a second polyanionic polysaccharide, thereby obtaining a dispersion liquid, a step of drying the dispersion liquid obtained, thereby obtaining a dried film, and a step of water-insolubilizing the dried film obtained with a treatment liquid containing a second acid anhydride, thereby obtaining the medical material.
