Rheological Properties of Isotactic and Atactic Propylene-Ethylene Copolymers
Abstract
The shear viscosity and extrudate swell of the isotactic and atactic fractions of propylene-ethylene copolymers produced with different ethylene content were measured at various temperatures and shear rates, using a capillary rheometer. In the isotactic fractions of these copolymers, the theoretical ethyl ene content was in the range of 4 to 10 wt%. The results indicate that the shear viscosity is not sensitive to composition for the isotactic …
