Abstract
The effect of temperature on transfer constants for different solvents in the polymerization of ethyl acrylate was observed. Activation energy differences (E~trS~ − E~p~) and frequency factors were computed. It is observed that high frequency factors are associated with high activation energies. Values of E~trS~ were calculated by an approximate method and were compared with the available data on methyl methacrylate, isobutyl methacrylate, and styrene.

Tbe free radical polymerization of ethyl acrylate was investigated in benzene and dimethyl formamide solutions at 50o. The effects of initiator and monomer concentration were studied over a wide range. The overall rate of polymerization was proportional to (initiator concentration) t ~' but not to t
An experimental study was performed to estimate the value of the lumped kinetic constant k p /k t 0.5 . This quantity was evaluated using the well-known conversion vs. time approach in dilute solutions using both azo-bis-isobutyronitrile and benzoyl peroxide (AIBN and BPO), and two different solvent
