Determination of the free radical lifetime in the polymerization process


Polimery 1988, No 10, 397


DOI: dx.doi.org/10.14314/polimery.1988.397

Summary

The stationary and non-stationary course of polymeryzation has been characterized with a particular attention being paid to the kinetics of the non-stationary photochemicaliy initiated process. The technique of „rotating sector” has been discussed and relations permitting determination by this method of the macroradical lifetime, t,have been cited. A method for the determination of t with the application of intermittent exposure Or on the basis of kinetic measurements in the period before attainment of equilibrium has been presented. The applicability of flash photolysis, pulse radiolysis and spektrometry in the studies on t-values has been also discussed.
