Abstract

This paper describes new techniques for evaluating orientation in polymer moldings. Injection moldings of isotactic polypropylene, a semicrystalline polymer, have been used to demonstrate the analytical procedures.

The reliability of numerical simulations of the injection molding process depends mainly on the rheological characteristics of polymers. The rheological characterization of a polymer for injection molding is commonly carried out by a capillary rheometer. However, in this method the measurement is ca
