Short chain branching of HDPE by 13C-NMR

Use of 13C-NMR to identify the type and relative quantity of short-chain branching in high-density polyethylene (HDPE) samples.

The prevalence of short-chain branching can have major effects on the properties of HDPE materials such as their crystallinity, melting point, density, and mechanical properties. The branching density and relative distribution of different length side chains can be determined by NMR using the Randall method.

The processed spectrum is delivered as an image file. Additional interpretation and raw data can be provided upon request.

Please contact Measurlabs' NMR experts to receive a testing plan tailored to your material and analysis needs. This analysis is only relevant to HDPE materials.
