Abstract

The effect of irradiation under vacuum on thermal properties and swelling behavior on poly(4-vinylpyridine) (P4VP) was investigated. The gel percentage in the irradiated P4VP films was determined by Soxhlet extraction. W spectroscopy was also used to determine sol percentage, which decreased as the radiation dose increased. The changes in thermal properties, such as glass-transition temperature (T-g), were followed by differential scanning calorimetry before and after Soxhlet extraction. The gels prepared after irradiation were characterized with respect to their swelling properties and network structures. (C) 2001 John Wiley & Sons, Inc.
