Plastics. Polypropylene (PP). Determination of isotactic index by low-resolution nuclear magnetic resonance spectrometry
This document specifies a relative method for the determination of polypropylene (PP) isotactic index by low-resolution pulsed nuclear magnetic resonance spectroscopy (LR-NMR).
This method enables the identification and coding of types H propylene (PP-H) plastics according to ISOÂ 19069-1.
This method is suitable for base polymers and is not applicable for mixtures.
The direct method for the determination of polypropylene isotactic index is specified in ISOÂ 9113 .
