✦ Synopsis


Almtract--The kinetics of ionic polymerization with instantaneous initiation, impurity transfer and chain transfer to monomer is studied by means of non-steady state procedure developed in previous publications. The expressions for molecular size distribution and other molecular parameters are derived rigorously. With the aid of the derived formulae, the molecular size distribution and the values of other molecular parameters for the resultant polymer can be calculated from the initial conditions of polymerization and reaction time.
