- Scope
- This document specifies three methods for determining the soluble content of polypropylene homopolymer or copolymer in xylene at 25 °C: --- Method A: chemical method; --- Method B: infrared spectroscopy; --- Method C: Low-resolution pulsed NMR method. Method A is the reference method for the calibration of method B and method C. This document is applicable to the determination of soluble content of polypropylene homopolymer or copolymer in xylene at 25 ℃. Materials such as additives soluble in xylene can affect the determination of xylene soluble content.
