ASTM D4827-03-Reapproved2009

Historical Standard: Standard Test Method for Determining the Unreacted Monomer Content of Latexes Using Capillary Column Gas Chromatography

ASTM D4827

Scope

1.1 This test method is for the determination of the unreacted monomer content of acrylic latexes. Monomers that have been successfully determined by this procedure include n-butyl methacrylate, n-butyl acrylate, styrene, and methyl methacrylate. The determination of other monomers has not been evaluated, but this test method is believed to be applicable. The established working range of this test method is from 100 to 1000 μ g/g, but there is no reason to believe it will not work outside of this range, provided that appropriate dilutions and adjustments in specimen size are made.

1.2 The unreacted monomer in acrylic latexes is expected to change with time and environmental factors. This time dependence of the determination may be seen as an artificially large deviation of results, making the test method mostly applicable for in-house quality control, where sampling and analysis conditions can be better controlled.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 7.
