This paper reviews various methods for measuring molecular alignment and various interpretations of results. It is emphasized that exact knowledge of the molecular arrangement in fibers is non-existent; many interpretations and models exist but none

When heated to high temperatures under zero tension, some of the molecules in oriented nylon 66 filters change from the elongated to the folded conformation, with no change in crystal orientation. This transformation is shown by a combination of stru

This discussion of the variability of polymer x-ray diffraction patterns tries to show that there is no simple definition of crystallinity when judged by x-ray diffraction, and that x-ray crystallinity may differ sharply from judgments of order by ot

The degradation resistance of matrix, fiber and composite systems which we have been studying as candidate orthopedic materials has been examined in two appropriate environments. Both resistance to steam sterilization in an autoclave environment and

Tests are described in which wet shrinkage is observed subsequent to strain annealing of nylon 6 fibers. The wet shrinkage studies demonstrated a large mobilizing effect by water present in the polymer structure even after very high temperature annea

A new technique was developed to study the molecular mechanics of highly oriented polypropylene during stress relaxation and creep. The polarized infrared spectrum was recorded while the polymer was under load. Stress relaxation effects were investig

Polypropylene has been fabricated into a different molecular morphology which shows the usual stiffness and high strength indigenous to this polymer, but which also exhibits surprising elastic behavior. Fibers and films in this form are extensible to
