The velocity of free-radical copolymerization is as yet not comprehensively understood in terms of the elementary processes of propagation and termination. A prevailing view of this classical subject may be that the propagation process is. in most cases, correctly described by the simple mechanism e

## Abstract Lack of termination in the โLivingโ polymer systems enables one to determine directly the absolute rate constant of propagation and of copolymerization. Anionic polymerizations in tetrahydrofuran are usually very fast, and a flow technique was developed to determine the rate of these re
## Abstract Rate coefficients of propagation, __k__~p,copo~, for MAโMMA, MAโDMA, DAโMMA, and DAโDMA bulk copolymerizations have been determined via PLPโSEC. The __k__~p,copo~ values are analyzed in terms of the terminal and penultimate unit effect models. Alkyl acrylate and alkyl methacrylate react
