Grafted radical (co)polymerization of water-soluble lignin derivatives with methyl acrylate was performed. The experimental results confirm the validity of the proposed mechanism of grafted radical (co)polymerization of methyl acrylate and sodium lignosulfonate in the presence of an initiator (hydrogen peroxide). It is shown that for the ratio of the components of the reaction mixture Z£2 in the system water-soluble copolymers are formed, molecular weight increases in 2,1 ÷ 2,8 times compared to the base polymer and the surface activity is reduced by more than 2 times. Found that the molecular weight of the copolymers LSNa – PMA is linearly dependent on the ratio of the components of the reaction mixture (Z), which allows to predict the value of the molecular mass for water-soluble copolymers.
