Notes:
A group of substituted phenols, quinone, and tropone were used to retard AIBN-initiated ethyl acrylate polymerization in ethyl propionate solution at 44.7°C. in the absence of oxygen. It was concluded that the efficiency of retardation depended upon the ability of the terminator to stabilize a positive charge on its reaction site in the transition state. Tropone was found to be a particularly good retarder. The radical-trapping efficiency of 2,2-diphenyl-1-picrylhydrazyl in this system was found to be 50-60%.
