Resumen:
This International Standard specifies four methods for the isolation of dry polymer from synthetic polymer latices containing anionic surfactants, for the purpose of subsequent testing. Tests that may be performed include the determination of the mooney viscosity, the bound-styrene or acrylonitrile content in the polymer chain or the mill shrinkage. Because of the wide variety of surfactants and stabliziers that are used in the manufacture of synthetic rubber latices, no one method is suitable for all latices. The methods given in this International Standard are suitable for a wide variety of latices, but their applicability should be confirmed for individual types. Latices containing non-ionic stabilizers, in particular, may be resistant to coagulation.
Das Dokument legt vier Verfahren zur Isolierung von trockenem Polymer aus Synthesekautschuklatices, die anionische oberflächenaktive Substanzen enthalten, zum Zweck der nachfolgenden Prüfung fest.
