文摘
- •
NMR and X-ray show high degree of orientation in crystalline and amorphous phases.
- •
NMR evidence of monoclinic structure in cold-drawn sample.
- •
Quantified degree of orientation from X-ray, obtained Herman's orientation function.
- •
Insight to exceptionally low permeability observed for the ultra-oriented film.
- •
Now possible to quantify taut-tie chain populations in fabricated or deformed PE.
