Abstract

There have been reports about the studies of simultaneous chlorination and carboxylation of polyethylene affected by gaseous chlorine and MALEIC ANHYDRIDE (MA) in carbon tetrachloride solution within the range of 90-110°C. In this study, photchemical chlorination of POLYISOBUTYLENE (PIB) in the presence of MA, and, in particular, the kinetics of this process was investigated. PHOTOCHEMICAL CHLOROCARBOXYLATION of POLYISOBUTYLENE was carried out in the mixture of carbon tetrachloride and chloroform. The order of the reaction with regard to reactant concentrations and the value of the reaction rate constant were found. By the method of quantitative description of substitution sites on the polymer chain, the ratio of the rate constants of the chlorination and carboxylation reactions was calculated. The effect of the neighboring unit, i.e., a decrease in the chlorination rate under the accepting effect of MALEIC ANHYDRIDE (scavenging effect) was observed. The time of the reaction corresponding to the maximum value of the SCAVENGING EFFECT was established.
