COMPOSITE MATERIAL CAPABLE OF FORMING HYDROGEL, AND HYDROGEL Russian patent published in 2007 - IPC C08L33/00 C08L39/00 C08L101/14 

FIELD: composite materials.

SUBSTANCE: composite material including bacterial cellulose (Acetobacter xylinum) and polymeric filler is characterized by that the latter is synthetic hydrophilic high-molecular weight homopolymer; or copolymer based on water-soluble vinyl-series monomers; or synthetic hydrophilic crosslinking copolymer based on water-soluble vinyl-series monomers and crosslinking agent having in its molecular structure two or more double bonds; or polyvinyl acetic acid or its (meth)acrylate; or polyethylene glycol or its (meth)acrylate; or polyethylene oxide or its (meth)acrylate; wherein molecular weights of non-crosslinked polymers are at least 50000. Indicated polymeric component is present in the form of polymeric lattice inside bacterial cellulose matrix and its concentration ranges from 10 to 98 wt %. Invention also discloses hydrogel obtained from above defined composite material.

EFFECT: increased resource of starting materials for preparation of hydrogels.
