WebPrevious research has studied reducing a polymer’s viscosity by mixing it with either solvent or other polymers. In one study, the viscosity of blends of polyamide 6 (PA-6)/LDPE was … Webviscosity, resistance of a fluid (liquid or gas) to a change in shape, or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow. The reciprocal of the viscosity is called the fluidity, a measure of the ease of flow. Molasses, for example, has a greater viscosity than water. Because part of a fluid that is forced to move …
