ABSTRACT:
An aqueous emulsion of an organic peroxide that is liquid at a temperature of 20.degree. C. and that is insoluble or has limited solubility in water is provided that has improved shelf-stability, shear-stability and process stability and has good dilutability and has a particle size of around 1.5 microns or less. The emulsion has from 1 weight percent of the emulsion to about 70 weight percent of the emulsion of an organic peroxide that is a liquid at 20.degree. C. and in particular that has a half-life exceeding 60 hours at 212.degree. F. (100.degree. C.) and 20 minutes at 300.degree. F. (149.degree. C.) The emulsion also has about 0.005 to about 15 weight percent of the emulsion of a nonionic emulsifier blend. The emulsifier blend has three emulsifiers selected from polyalkylene glycol ethers, dialkylaryl polyether alcohols, and polyoxy-propylene-polyoxyethylene condensates and the like nonionic emulsifiers having a particluar HLB range for each of the three emulsifiers. The remaining weight percent of the emulsion is water.
The method of preparing the aqueous emulsion involves the addition of the emulsifier blend to the liquid peroxide. One of the emulsions is split into two portions for the addition.
The aqueous organic peroxide-containing emulsion is incorporated into a sizing composition for treating glass fibers to produce treated glass fibers for use as reinforcement in polymers.
