摘要：

The accurate measurement of the orientation and draw ratio of polymer chains in the amorphous phase of the semicrystalline state using quadrupolar nuclear magnetic resonance (NMR) is presented. Polyamide-6 (PA6) materials, bulk and fibers, swollen with a 20% formic acid solution were studied using the NMR method. The swelling ratio was 20% and independent of the draw ratio. Drawing at high temperature is not affine for semicrystalline elastomer polyamide.
