SOLVENT EFFECTS AND INITIATOR EFFICIENCY IN THE BENZOYL PEROXIDE-DIMETHYLANILINE SYSTEM

摘要

The second order reaction between benzoyl peroxide (BZ02) and dimethylaniline (DMA) has been followed in two ways: directly by measuring undecomposed peroxide, and indirectly, by observing changing polymerization rates while the pair was being used as polymerization initiator. The latter method was checked by using initiators of known decomposition rate and afforded a rapid reasonably precise method of obtaining initiator efficiency. Efficiencies were measured for bulk and solution polymerization from 0°to 80℃
