| Abstract | ||
| This study was carried out to improve resistance to weathering Conditions especially ultra energy rays through physical blending with polyol monomer of 10%,20%,and30% ratios.The molding casting method was used to manufacture the samples which were exposed to high tempreture (110c) for (85)hours. The morphological study showed the nature of the distribution of polyol molecules and their miscibility with unsaturated polyester, as well as, the polymer mixtures surface..Also The photo graphs after radiation revealed that the surface showed aclear difference according to mixing ratios and the extent of degradation factors. The samples were continuosly exposed to uv-rays after radiation for 300 hours wavelength 245 nm, the photographs showed clear difference in the synthesized sample surface due to photodegradation which observed by uv-spectra. The percentages 20% and 30% showed a great sensitivity towards light . These samples gave swelling as a result of disohants indicating their degradation was faster than other samples.( if compared with the results of the virgin sample). It was proved that polyol with flexible properties can give improvement to the properties of unsaturated polyester of Hard properties via blending by 10% and lower ratios that give stabilization to the studied samples . | ||
