Abstract
High molecular weight, water soluble polymers are dissolved to form liquid solutions at relatively low polymer concentrations and solid, water-plasticized composites at higher polymer concentrations by admixing finely divided polymer particles with ice particles at temperatures below, and preferably far below, the freezing point of water. The admixture is then allowed to warm causing the ice to melt and the polymer to dissolve in the water.
