✦ Synopsis

A mathematical model is proposed for the batch polymerization of butadiene, isoprene, and styrene with alkyl lithium initiator. All three polymerization systems were considered with polymer association and no termination. The fact that first order and l/nth order rates of initiation have been observed is explained and equations are developed which describe the system when both mechanisms may be controlling. The results calculated from the integrated equations compared favorably with experimental data obtained by Henry L. Hsieh [13]. The mathematical procedure employed here enables fairly easy computer calculations of the molecular weight distributions which is essential for the evaluation of any polymerization system.
