| Abstract | ||
| The aim of this reseach is to improve polyester resin application properties in resistance of weather conditions since it used for coating processes of surfaces which are faced to the sun radiation . The samples have been produced by mixing the polymer with monomer acrylonitrile at ratios (10%,15%,20%) to determine the effect of this monomer on to resistance of the surface upon optical rays. This study gives to measure the absorbance a good result of resin resistance to degradation from the mixing after exposed it to a uv.radiation with wave length254nm for300h continuously. The best mixing ratio of monomer 15%from monomer. In other hand, processes grading the oxidations on surface. Finally, these processes have been studied by using the spectral photometer obtained and transmitter - reflector optical microscope before and after irradiation. | ||
