Some biological polymers – casein, gelatin, are used in various adherent systems like adhesives for cardboard, paper, leather finishing and various paints. However,their use is constrained by the high brittleness of the films, which makes it necessary to change their properties by chemical modification. In this paper we realized the synthesis of aqueous dispersions of copolymers based on butyl acrylate and protein molecules. Kinetics of graft copolymerization of butyl acrylate with protein macromolecules are studied. Established the amount of graft copolymer by selective dissolution. The copolymer composition was determined by the number of mineralized nitrogen. The work investigated the influence of various factors on the reaction process of radical copolymerization in emulsion in order to obtain the maximum yield of the graft copolymer. The synthesized polymer dispersions have good adhesion to various substrates (for glass, paper, leather and artificial leather, metal, for fabric-based).
