摘要：
UV-induced photodegradation has been studied of films of polyurethanes synthesised from (renewable) vegetable materials, namely rapeseed and sunflower oils. The techniques utilised were principally IR and UV-visible spectroscopy. UV(B)-photolysis of the cured films gave rise to IR bands in the carbonyl region at ca 1706 cm(-1) and a UV band at 310 mn attributed to formation of a quinone methide, an assignment supported by the development of new IR bands at 1595, 1650, and 1695 cm(-1) which are typical of this chromophore. In addition, intensification of a band at 1171 cm(-1) is attributed to cross-linking of the soft segments in the polymer.
