**Abstract**
 The suitability of oxalic acid as a crosslinking agent for PVAl was investigated. Curing was carried out at temperatures from 100 to 140 degrees C over a range of time periods and oxalic acid concentration was varied from 3 to 70 percent. Optimum curative dose and curing conditions were evaluated by systematic swelling measurements in hot and cold water. Crosslinked PVAl films were characterised by FTIR spectroscopy to identify the nature of functional groups therein and the heat stability and phase morphology of the films investigated. 28 refs.
