Abstract

This study concerns slow initiation of living polymerization of isobutylene by 1-methoxy-1-methylcyclohexane/TiCl4 and trans-2,5-diacetoxy-2,5-dimethyl-3-hexene/BCl3 combinations. Experimental data indicates that the average molecular weight (M̄n) and the number of polymer molecules (N), consequently initiating efficiencies (Ieff), increase monotonically with j, the number of incremental monomer addition. However, as a result of slow initiation, higher than ideal M̄n's, polydispersities (M̄w/M̄n), and lower than ideal Ns are obtained.
