Photo-oxidative degradation of polyurethanes based on hexamethylene diisocyanate with different oligoether components was investigated using IR spectroscopy and dynamic mechanical analysis. The cross-linking density of highly cross-linked polyurethane based on an oligoether triol of molecular mass 500 tended to increase during photo-oxidation. A polyurethane containing esters was more stable than that based on an oligoether diol of similar molecular mass.
