Microporous polyurethane elastomer, based on 4,4′‐diphenylmethane diisocyanate and polyester polyol Bayflex 2003 (Bayer AG), was degraded by phosphoric acid esters (CH 3 CH 2 O) 3 P(O) and (ClCH 2 CH 2 O) 3 P(O) at 180°C. Structure of degraded products was investigated by means of 1 H‐, 13 C‐, and 31 P‐NMR spectroscopy. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 76: 886–893, 2000
