DEGRADATION OF POLYMER-SOLUTION FILAMENTS

The laws of thinning and breaking of a caplliary filament of a high-mo lecular-weight polymer solution were experimentally and theoretically investigated, Physical mechanisms involved in the filament breaking ar e analyzed. Measurements of the time variation of the capillary filame nt diameter, performed for a variety of polymer solutions, gave result s consistent with the theoretical model developed, Possibilities to us e observations of the formation, thinning, and breakage of polymer fil aments for evaluation of the rheological characteristics of polymer so lutions.
