Determination of Xylene Solubles in Polypropylene
Application Note Nov 26, 2010
‘Xylene solubles’ is an historically established term denoting the percentage of soluble species in polypropylene homo- and co-polymers. This measure is widely used for product quality control and monitoring physical properties of the polymer during synthesis and processing.
This application note demonstrates how, in contrast to the standard wet chemistry method and the FTIR technique, low resolution Nuclear Magnetic Resonance provides a quick and direct method for determination of the xylene solubles content in polypropylene.
