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 The theoretical approach to freeโ€radical 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__
