Abstract
The authors investigate the electrochemical polymerization of an unsaturated isocyanate-containing oligomer in solvents with different donor capacity (dimethylacetamide and acetonitrile) as a function of the concentration of the starting product, temperature and density of current. It is shown that in dimethylacetamide the polymerization of such an oligomer is accompanied by simultaneous conversion of the free isocyanate groups and unsaturated bonds with formation of an insoluble network polymer. In acetonitrile electrochemical polymerization of the oligomer proceeds with the formation of two fractions — fraction soluble in organic solvents with M=10 3 formed through polymerization via the free isocyanate groups (the unsaturated bonds are located in the side chain of the oligomer) and an insoluble polymer the network of which is formed by conversion of the free isocyanate groups and unsaturated bonds.
