1 Scope
GB/T 29613 provisions of this section under the same test conditions, pyrolysis gas chromatography according to FIG identified raw rubber, vulcanized rubber or sulfur
Of the polymer gel and single and methods used. Qualitative analysis of this section may be used for single or rubber and rubber, but there are certain polymers

This section applies to the identification of a single polymer. When the polymer mixture has a pyrolysis chromatogram characteristic of hydrocarbons, the
This method is also applicable to the identification of the polymer mixture, described in detail in Chapter 4. This method is also applicable to the identification of other types of polymers, but
Analysis should be verified.
