Abstract

Improvements introduced in the process of polymerizing ethylenically unsaturated materials capable of free radical type polymerization with a free radical type initiator, whose improvements comprise carrying out said polymerization in the presence of an alkaline buffer reagent and an initiator system comprising, in in combination, an acid anhydride and an organic peroxyacid, said anhydride and peroxyacid being present in sufficient amounts to polymerize the ethylenically unsaturated material.
