Abstract
An aqueous emulsion of a solid, water insoluble or limited water soluble organic peroxide is provided that has improved stability, dilutability and safety but still having an average particle size of 1.5 microns or less and a good particle size distribution. The emulsion has from about 10 weight percent of the emulsion of a solid peroxide selected from the group of hydroperoxides .alpha., -oxy and .alpha.-peroxy hydroperoxides, dialkyl peroxides, aldehyde and ketone peroxides, diacyl peroxides, peroxyesters, peroxy acids, peroxydicarbonates, monoperoxycarbonates and perketals. The emulsion also has a hydrocarbon solvent having a high kauri-butanol number if the organic peroxide has a substantial amount of aromaticity and a low kauri-butanol number if the organic peroxide has little or no aromaticity and one or more nonioic emulsifiers and at least about 20 weight percent of water. The method of preparing the emulsion involves solubilizing the peroxide in the hydrocarbon solvent and adding the emulsifiers and emulsifying. The emulsion of organic peroxide can have many uses including uses in vinyl and diene polymerization, and being used in a sizing composition for glass fibers to produce treated glass fiber strands that can be used in polymer reinforcement such as the reinforcement of polyolefins, polyamides and polyester.
