Real-Time X-Ray Scattering Study of Processing of Eight Performance Thermoplastics.

Abstract

The purpose of the research was to use real time X-ray scattering: (1) to assist in development of a model for the shrinkage of thermoplastic polymers during processing, and (2) to study the kinetics of crystal structure development. The principle tasks involved real-time X-ray scattering experiments. The secondary tasks involved characterization studies of the materials. We are using real time X ray scattering to study the shrinkage of crystallizable thermoplastic polymers during heat treatment. Most processing models in use today do not use data collected in situ. The matrix shrinkage is determined in real time, directly from x ray scattering. The evolution of cell structure that develops during crystallization can be detected by small angle and wide angle real time x ray scattering.
