| 摘要 |
The instant invention is directed to a method for preparing free-flowing, water-soluble polymer gels comprising: (a) reducing the size of water-soluble polymer gels by a size-reduction means, so as to produce polymer gel particles which are less than 1/2 inch in their longest dimension; and (b) adding to the size-reduced polymer gels of Step (a) 0.001 to 20 percent, by weight, of an amphipathic compound, thereby reducing the adhesion of said gel particles to themselves and other substances. The instant invention is also directed to a free-flowing, water-soluble polymer gel admixture comprising: (a) size-reduced, water-soluble polymer gel particles, wherein said gel particles are less than 1/2 inch in their longest dimension; and (b) an amphipathic compound.
