Synthesis of poltalkylenearyls Communication 6. Effect of the relative amounts of reactants on the course of the copolycondensation of benzene and chlorobenzene with 1, 2-dichloroethane

Abstract

1. The effect of the original proportions of reactants on the course of the copolycondensation of 1,2-dichloroethane with benzene and chlorobenzene was studied. 2. The relative activity of chlorobenzene was determined (the activity of benzene being taken as unity), and it was shown that the relative activities of these aromatic compounds do not depend on their concentrations in the original mixture. 3. An empirical equation was found for the composition of the copolymer as a function of its yield and the relative amounts of aromatic compounds in the original mixture. 4. Increase in the dichloroethane content of the reaction mixture results in reduced yield of copolymer.
