摘 要：<正> The yellowing of clear GRP in outdoor applications resalts primarily from photo-oxidation ageing of clear UP （unsaturated polyester） resins. In this paper, the chemical changes in the molocular structures of clear UP resins dtring photo-oxidation ageing are studied by FTIR spectra, and some of the essential reactions in the processes are. discassed. Since the re（?）o（?） betweea "yellowing" and ageing processes is determined, We have a theoretical basis on which we can effectively swarch for methods of anti-weathering for clear UP resins.
