Abstract
The dimer content in alpha, beta- ethylenically unsaturated ketones may be reduced by treating the ketone with a peroxide of the formula ##STR1## wherein R.sub.4 is a C.sub.1-6 branched or straight chain alkyl radical or a C.sub.6-10 aromatic radical and n is 1 or 2. The treated ketone has a faster rate of polymerization with other ethylenically unsaturated monomers.
