EXTENDED POLYACRYLIC ACID BASED BINDER COMPOSITIONS

摘要

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 a s lignin, low molecular weight starch and soybean protein. The extended binder composition of the present invention provides a lower cost binder compositio n without degrading the performance and may be selected to alter one or more characteristics of the basic binder composition such binder wetting, emulsio n compatibility, dust suppression and wash water flow properties.
