The attainable ยฎalues of molecular-weight distribution MWD specified by the degree of polymerization and the polydispersity in a batch free-radical polymerization reactor are described. The two-step method based on the quadratic profile of the instantaneous degree of polymerization is used to obtain

## Abstract In this part of the series, the influence of polyfunctional chain transfer agents with transfer constant __C__ โค 1 on the molecular weight distribution was studied. The analytical expressions for the numberโ and weightโaverage degree of polymerization, and dispersion index were derived
## Abstract The theoretical approach to freeโradical polymerization in the presence of polyfunctional transfer agents can be derived in a simple way if the effects of primary chains and termination reactions are neglected. Under these conditions, and for values of the chain transfer constant __C__
