Rubber - Identification of polymers (single polymers and blends) - Pyrolytic gas chromatographic method

Abstract

This Standard specifies a method for the identification of polymers, or blends of polymers, in raw rubbers and in vulcanized or unvulcanized compounds from pyrograms (pyrolysis-gas chromatographic patterns) obtained under the same conditions.This allows qualitative identification of single rubbers or blends, with exceptions discussed below. The method applies first and foremost to single polymers. When the program indicates a characteristic hydrocarbon, the method is also applicable to blends. For details, see clause 4. The method may be also applicable to other types of polymers, but this must be verified by the analyst in each particular case. The use of this Standard pre-supposes sufficient working knowledge of the principles and techniques of gas chromatography to enable the analyst to carry out the operations described and to interpret the results correctly
