Yield analysis of copolymers: effect of temperature, feed ratio and initiator concentration on the copolymerization

Abstract

Copolymerization of pyrrole and aniline was carried out using chemical methods. The synthesis was carried out at different temperatures for different pro portions of the monomers. The monomer reactivity ratios for pyrrole and aniline were calculated as 5.2 and 0.19, respectively, by using the low conversion analysis method. In addition, the same was done for two different concentrations of the initiator. The graphs for percentage conversion were plotted for various combinations of tem perature, feed ratio and initiator concentration. Thus, an effort was made to study the impact of various parameters on the process of copolymerization.
