Abstract

The kinetics, molecular weight averages, and the average degree of branching, DB, are calculated for the self-condensing vinyl copolymerization (SCVCP) of a vinyl monomer M with an inimer AB* in the case of different reactivities of active species. Emphasis is given to two limiting cases: formation of macroinimers occurs if the monomer M is more reactive than the vinyl groups of inimers or polymer, and hyperstars are formed in the opposite case. It is shown that the kinetics, the molecular weight averages, and the average degree of branching strongly depend on the relative reactivities of monomer and inimer. Comparison with experimental data shows that consistent fits of the reactivity ratios can be obtained.
