ABSTRACT:
New dialkyl esters of monoperoxyoxalic acid which have a tertiary alkyl group in the perester part of the molecule while the other alkyl group is a long-chain, primary alkyl group. The compounds give rise to radicals at heating and are useful as initiators for the polymerization of ethylenically unsaturated monomers, particularly for the polymerization of vinyl chloride.
