Abstract
The present invention provides a variety of extended polyacrylic acid based binder compositions comprising a low molecular weight polyacrylic acid (typically hypophosphite or sulfite terminated), a crosslinking agent (such as triethanolamine or glycerol) and one or more water soluble materials, such as lignin, low molecular weight starch and soybean protein. The extended binder composition of the present invention provides a lower cost binder composition without degrading the performance and may be selected to alter one or more characteristics of the basic binder composition such binder wetting, emulsion compatibility, dust suppression and wash water flow properties.
