FIELD: paper-and-pulp industry.
SUBSTANCE: adhesion binder that can be used in paper-coating composition to impart to the latter rheological and other properties is prepared by alkaline dispersion of soya protein material and polyacrylate, which comprises stirring of polyacrylate with soya protein material at a temperature and for a time sufficient for molecules of polyacrylate and soya protein material to be mutually interlaced and jointly precipitated at isoelectric point of soya protein.
EFFECT: improved quality of paper-coating compositions.
