Polyethylene Branching Analysis by NMR

Identification of unknown polyethylene (PE) polymers by NMR.

Unknown polyethylene samples can be identified by NMR chain branching analysis. 13C NMR can be used to determine the nature of an unknown polyethylene (HDPE, LDPE, LLDPE) and can identify and quantify the types of branching present.

The image on this webpage shows an LDPE which contains a number of different types of branches (methyl, ethyl, butyl, pentyl and hexyl and longer) and an LLDPE, prepared from ethylene and hexane-1 which contains only butyl branching.
