ABSTRACT:
Polyoxazolines, such as poly-2-ethyl-2-oxazoline, having a weight average molecular weight in the range of from about 1,000 to about 150,000, are effective as dispersing agents for particulate matter found in starch/clay coatings and protein/latex clay coatings for paper. Usually, 0.005 percent to about 2.0 percent polyoxazoline, based on the total weight of the binder, effectively reduces the viscosity of said paper coatings, allowing the use of higher solids in the coating composition.
