Four new peroxy esters, of which three compounds have the carboxyl groups in the neighboring positions of the peroxyl group, were synthesized in good yields. t-Butyl 2-(carboxy) cyclohexaneperoxy carboxy late and t-butyl cis-6-carboxy-3-cyclohexene-1-peroxy-carboxylate were prepared by adding t-butyl hydroperoxide to each corresponding dicarboxylic acid without solvent, t-Butyl o-carboxyperbenzoate and 2-butyl o-chloroperbenzoate were prepared by adding t-butyl hydroperoxide to phthalic anhydride and o-chlorobenzoyl chloride, respectively. The polymerization of styrene was carried out by using three peroxy esters having the carboxyl groups as the initiators. The polymerization was initiated by the peroxy esters, but it was slow compared^ with that initiated by azobisisobutyronitrile under the same conditions. © 1987, The Chemical Society of Japan.
