Abstract : A high polymer suspension including a polymer; a liquid carrier; a fibrous silicate material; and an organic derivative of clay. The polymer is preferably a polyacrylamide, the fibrous silicate material a chrysotile asbestos, and the organic derivative of clay, dimethylbenzloctadecyl ammonium hectorite. The invention is a high polymer suspension which includes a polymer such as a polyacrylamide; a liquid carrier, a fibrous silicate material, such as chrysotile asbestos; and an organic derivative of clay, such as dimethylbenzyloctadecyl ammonium hectorite. The present invention is very stable, inexpensive, and retains a high percentage of polymer in suspension. The combination of the chrysotile asbestos and Bentone 27 results in a synergistic effect which gives the invention its high suspending capability, in the order of 30% to 50% of polymer by weight. The present invention may also have use in fire fighting applications for producing an extremely log stream of water or for reducing pumping requirements.
