Abstract : Unsaturated polyesters have been extended with high levels of water. The water-in-oil emulsions resulting from mixing polyester and water have been conventionally cured with peroxide-promoter combinations to composites with unique property combinations. Screening studies demonstrated that physical strengths of Water-Extended Polyester (WEP) composites are dependent on resin selection, percent water, percent styrene, catalyst and promoter selection, and choice of emulsifier. By the use of properly formulated resins, the need for an emulsifier was eliminated. In order to fulfill contractual requirements of filling test craters at up to forty cubic feet, a laboratory-scale continuous mixer capable of one gpm output was initially designed and fabricated as a prototype for a subsequent larger ten gpm unit. Initial test pours were conducted using benzoyl peroxide as catalyst. Subsequent test pours were conducted using non-hazardous liquid peroxide catalyst. The materials cost of WEP composites were established.
