This report describes research work conducted to develop an improved polyvinyl acetate emulsion. Various manufacturers were contacted for information, recommendations, and samples of basic polyvinyl acetate systems. Some systems were modified with various additives. Tests were conducted on both modified and unmodified samples. These tests included determination of physical properties with particular emphasis placed on toughness. Environmental tests included exposure to ultraviolet light and water spray, soil bacteria, and fungi and heat aging. Modifications studied included viscosity, plasticizers, and fungicides. The above data were analyzed and six of the most promising formulations were submitted to the U. S. Army Engineer Waterways Experiment Station WES for evaluation. Laboratory screening tests and weathering tests were performed on these materials at the WES. The WES completed evaluation of the formulations and requested that procurement specifications for formulation 034001B be prepared. Procurement specifications were prepared using analysis of the 034001B test data. The specifications contain both physical and chemical properties of this material.
