Abstract
Abstract COMPOSITIONS OF LIQUID DIALKYL PEROXYDICARBONATE, E.G., DI-N-PROPYL PEROXYCARBONATE, AND ALKYLATED CYCLOHEXANE DILUENT, E.G., METHYLCYCOLOHEXANE, ARE DESCRIBED. THE COMPOSITIONS REMAIN MISCIBLE AT LOW TEMPERATURES, E.G., -35* C., ARE SUITABLE FOR USE AS POLYMERIZATION INITIATORS FOR THE PRODUCTION OF POLYMERS USED IN FOOD WRAPPING AND ARE SUBSTANTIALLY LESS HAZADOUS THAN THE NEAT (100%) DIALKYL PEROXYDICARBONATE.
