A cursory /sup 13/C NMR analysis of Halthane pre-polymer components was initiated for the purpose of establishing a data file for potential use as a product qualification base. A /sup 13/C analysis of the hydrolysis of 4,4'-diphenylmethane diisocyanate (MDI) was initiated. Chloroform extraction of the cured polymer produced an approximate 1% of polymerized Halthane.
