FIELD: chemistry.
SUBSTANCE: disclosed is an adhesive composition containing a) polyamidoamine-epihalohydrin polymer with molecular weight 2000-100000 g/mol, which is a product of reaction of epichlorohydrin and a product of polycondensation of polyamine and polycarboxylic acid, and b) protein or lignin, where the weight ratio of a) to b) ranges from 100:0.1 to 0.1:100. Also disclosed is a version of the adhesive composition which contains a low-viscosity polymer, use of the disclosed composition to glue wood and cellulose, a method of producing a thermosetting product using the disclosed composition and articles from wood, which are glued to each other using the disclosed composition.
EFFECT: adhesive compositions have controlled viscosity and prolonged stability during storage, which makes easier their use and widens their field of use.
