Abstract

Contributions of the covalent and ionic species to the chain building in cationic reversible polymerizations are analyzed by means of Monte Carlo simulations and by solving the formulated set of equations. The validity of the equation for the contribution of covalent propagation, derived for reversible polymerization with simplifying assumptions, is discussed. It is shown that repeating units incorporated into the chain by covalent propagations are distributed uniformly only when direct monomer insertion into covalent bonds is not possible, or when intramolecular interconversion of covalent and ionic species is very fast in comparison with propagation.

## Abstract The problem of computing of the covalent and ionic species contribution to the chain building in propagation is discussed, and it is shown that under certain conditions the reversibility of propagation does not influence the contribution of the given species.

## Abstract Divalproex sodium extendedโ€release (Depakote^ยฎ^ ER) is a once daily (QD) formulation for valproic acid that was developed to improve patient compliance and to reduce side effects compared with the standard twiceโ€daily (BID) delayed release (DR) formulation (Depakote^ยฎ^ tablets).
