Abstract

An unusual depression of phase transitions was observed in a polymer composite system, when 4,4'-bis(2- methylpropenoyloxy)-biphenyl (BMB) was UV polymerized in a cholesteryl propionate matrix. Our analysis indicates that different chemical processes take place simultaneously during the photo polymerization. One is the polymerization of BMB leading to the formation of a polymer network. Independently from this, cholesteryl propionate suffered some chemical changes and, as main product, 7-hydroxy- cholesteryl propionate formed. This compound was isolated and its structure established by IR, NMR and MS spectroscopy.
