INFRARED AND GAS CHROMATOGRAPHIC STUDIES OF MAGNET-WIRE ENAMELS.
Abstract
Quantitative methods were developed for measuring performance related characteristics of magnet-wire enamels such as residual-solvent content, degree of conversion upon curing, and changes in molecular structure with thermal aging. Results of both infrared absorption and gas chromatographic studies of cured and thermal aged polyimide and Formvar resin enamels are reported. Sample preparation techniques are described. Correlations are made with standard performance tests such as weight loss on heating and breakdown voltage. (Author)
