Glass, zinc, copper, or tin supports were shown to have a sensitizing action on the photochemical degradation of a polyurethane prepared from tolylene diisocyanate and trimethylol propane. It was shown that photodegradation of the polyurethane was linked with the breakdown of the isocyanate groups. It was concluded that a two-photon mechanism of heterogeneous photodegradation of the polyurethane operated.
