Determination of Water in Rubbers.
Abstract
A comparative study has been made of 5 methods for determining moisture in rubbers. The methods are distillation (Dean and Stark), solvent extraction followed by gas chromatography, Karl Fischer titration, the oven gas chromatographic method of Jeffs, and weight loss over phosphorus pentoxide. The weight per cent water contents determined by each method are tabulated. The rubbers are referred to by their generic names, and the compositions were chosen so that they would be typical examples. It is impossible, from these results to define an absolute water content for each rubber. In all the methods the water is first extracted from the rubber and then determined, and the result obtained depends on the temperature and on any solvent used on the extraction.
