THE QUANTITATIVE ANALYSIS OF VULCANIZED RUBBER BY THE ATTENUATED TOTAL REFLECTION OF THE INFRARED SPECTRUM

Abstract

There has been no simpler method of canalizing vulcanized rubber, but we could canalize it by adopting the process of the attenuated total reflection of the infrared spectrum (ATR process). Two kinds of rubber were blended in various weight ratios and were vulcanized. From the chart of the attenuated total reflection of the infrared spectrum of these samples the strength of key band of rubbers was measured. We calculated the relation between the key band of rubber and the blended rubber weights. The results of the quantitative analysis were very satisfactory. The error in these measurements was about 2%.
