Liquid resins used for molding composite structures are a significant source of VOC and hazardous air pollutant (HAP) emissions. One method of reducing styrene emissions from vinyl ester (VE) resins is to replace some or all of the styrene with fatty acid-based monomers. VE resins with no more than 20 wt % styrene were prepared using methacrylate terminated fatty acids. The viscosities of these resins were below 500 cP, allowing the use of vacuum assisted resin transfer molding for composite production. Composite panels were made from these resins using E-glass at ∼ 0.4 vol. Fatty acid monomers can be used to produce affordable low VOC/HAP vinyl ester resins without a loss in performance. This is an abstract of a paper presented at the AIChE Annual Meeting and Fall Showcase (Cincinnati, OH 10/30/2005-11/4/2005).
