Abstract

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 ISO 19069‑1.

This method is suitable for base polymers and is not applicable for mixtures.

NOTE The direct method for the determination of polypropylene isotactic index is specified in ISO 9113.
