Procedure

In Example A, the procedure of WO 01/32613 was repeated. First, a solution of Na2O2 was prepared by combining 108.3 g of demineralized water, 18.5 g of NaOH-33 solution, and 3.7 g of the aqueous H2O2. A second reactor was charged with 33.3 g of demineralized water, 27.7 g of the PVA solution, and 16.3 g of isobutanoyl chloride while controlling the temperature between 5–10° C. Next, the Na2O2 solution was dosed while the system was homogenized. No diisobutanoyl peroxide was obtained and only an aqueous phase formed.
