ABSTRACT:
Disclosed are high concentration aqueous dispersions of normally solid organic peroxides using a dispersion agent comprising an alkylaryl polyether alcohol and an oxyalkylated phenolic resin. Optional components such as thickening agents, anionic emulsifiers and a partial ester of a carboxylic acid copolymer may also be included. Dispersions having concentrations of up to about 65% weight percent organic peroxide can be prepared. Dispersions having concentrations of up to about 40 weight percent organic peroxide are sprayable. Also disclosed are the curing of polyester resins and the suspension polymerization of vinyl monomers using these dispersions.
