PHYSICAL CHEMISTRY OF HIGH POLYMERS
Abstract
The previously reported theoretical consideration of stationary-state conditions in an isothermal polymerization has been extended to cases where the reaction temperature rises linearily throughout polymerization. A solution has been obtained for a criteria for the existence of stationary-state conditions. This work indicates that the stationary-state situation prevails in the differential thermal analysis studies on styrene polymerization within the limits of conditions presently used. Differential thermal analysis studies of the thermodynamics and kinetics of styrene polymerization in solution has yielded thermograms which are reasonably consistent and reproducible over the entire temperature span of the reaction. Rate data appear reasonable for temperatures up to 100 C, but above 100 C the rate slows appreciably. A rather detailed examination of the entire system has not yet yielded a solution to the problem.
