| Abstract | ||
| In this work a polymer blend from unsaturated polyester resin (UPE) and polystyrene (PS) was prepared by hand mixing. The pellets of polystyrene was dissolved using toluene, the result liquid was added to the resin with different weight percentages (0,5,10,15,20)%. Compression and Shore (D) hardness tests were carried out on the prepared samples before and after the immersion into distilled water, (H2SO4) acid and (NaCl) salt with normality (0.25). (Stress-strain) behavior of the blend specimens immersed in different environment shows clear change in the behavior under effect of various environments. The results exhibited obvious decrease in hardness values with increasing the polystyrene ratio of blend. After the immersion of specimens into water, acid and salt solutions, it was found that there is little effect for the immersion time factor on those values for (6 weeks). | ||
