GLC Analysis of decomposition products of dicumyl peroxide has been used for determination of relative rate constant of hydrogen transfer of cumyloxyl radicals with tetrakis(allyloxymethyl)-methane. This constant is 15 times higher than that with 2,2,4-trimethylpentane. In the reaction an only small portion of the oxyl radicals (up to 15% of total amount) is consumed by addition to allyl groups of the monomer even when a great excess of the latter is present in the reaction mixture.
