Determination of polyethylene branching through computerized13C NMR analysis

  • H. N. Cheng
Analysis

Summary

Computerized analysis has been devised to maximize the information content available from the13C NMR spectrum of low-density polyethylene. Both long and short chain branches can be readily quantified. Two types of long chain branching have been identified, from which the number-average molecular weight and the average size of the long chain segments can be determined. The mathematical expressions relating these parameters have also been derived.
