CHAIN FOLDING AND UNFOLDING IN POLYETHYLENE (I)
The present paper gives a method to evaluate fold-content, Cf in polyethylene (PE) from IR measurement (1200-1400cm-1). Solution-grown crystals of n-paraffin and PE were adopted as standard specimen containing no fold (Cf=0) and 100% fold (Cf=1.0), respectively and mixtures of these substances were...

| Zusammenfassung: | The present paper gives a method to evaluate fold-content, Cf in polyethylene (PE) from IR measurement (1200-1400cm-1). Solution-grown crystals of n-paraffin and PE were adopted as standard specimen containing no fold (Cf=0) and 100% fold (Cf=1.0), respectively and mixtures of these substances were used for the determination of constants, k and K, in Koenig's equation. The values of Cf obtained from two pair of absorption bands (from each sample) showed good agreement for various PE samples. |
