BSI | 2020 | 16 |
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 provides for 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.
The direct method for the determination of polypropylene isotactic index is specified in ISO 9113.
