Production of oligomers capable of polymerization on the basis of chloroparaffins and some of their properties

1. Methacrylate chloroparaffins with various contents of methacryl groups and double bonds in the basic chain of the molecules were produced by the reaction of nucleophilic substitution of part of the chlorine atoms in chloroparaffins KhP-15-52.3 and KhP-25-44.5 bymethacryl groups by their reaction with potassium methacrylate in the presence of dimethylformamide (DMF) as the electron donor solvent. 2. Decreasing the DMF concentration in the reaction mixture leads to a change in the ratio of methacryl groups and double bonds in the basic chain of the methacrylate chloroparaffins in the direction of an increase in the fraction of methacryl groups. Oligomers retaining the ability for polymerization and, moreover, containing the least number of double bonds in the basic chain (0.05 per molecule) are obtained at a DMF: methacrylic acid ratio close to equimolar. 3. The methacrylate chloroparaffins obtained polymerize under the influence of radical-type initiators. In a number of cases there is an inhibition of the polymerization process. Hypotheses were advanced on the causes of this phenomenon.
