Abstract
The present invention is a continuous process for preparing formulations useful for making filled polymer carpet backings. The present invention particularly incorporates polyisocyanate as a reactive diluent in a continuous process for preparing filled polyurethane polymers. Use of the present invention allows production of carpet backings that incorporate high loadings of filler materials.
