描述了在注射成型过程中玻璃化的无定形聚合物熔体中的取向发展。取向发展的预测是基于这样的论点，即应力光学定律在熔融状态下是有效的，并且在玻璃化时保持适合于应力水平的双折射值。这一理论相比，在注塑件中确定的双折射分布。
Orientation development in amorphous polymer melts being vitrified in an injection molding process is described. Predictions of orientation development are based on the argument that the stress‐optical laws are valid in the molten stare and birefringence values appropriate to the stress levels at the time of vitrification remain. This theory is compared to birefringence distributions determined in injection molded parts.
