Polymerization of styrene to high degrees of conversion (up to 99.8%) was carried out. The obtained polystyrene was fractionated by distribution between two liquid phases and also by fractionating precipitation. Molecular weights of the fractions were determined and the molecular weight distribution
## Abstract A method is described which allows the precise estimation of molecular weight distribution parameters __p__ and __A__ which pertain to freeβradical polymerizations. Thus, expressions are developed which allow the estimation of (1 β __p__) by means of a programmable calculator using mole
