Abstract
POLYMERIC gel systems may be formed either by cooling a polymer solution, or by swelling a suspension of solid polymer particles in a suitable solvent. These two types of gelation process differ in one fundamental respect. Gel formation from solution is usually a thermoreversible process, and on warming, the system reverts back to a solution. On the other hand, gelation by swelling is thermally irreversible, and scarcely any shrinkage occurs on cooling.
