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.
