| Abstract The aim of this work to study the effect of different liquids and chemical solutions on polymers. The polymers was choosing commercially is important (unplasticized PVC, plasticized PVC and polyester). The results show the color change in samples after immersed in solution and in the same time show change in weight, the concentrated acid show more effect than anther solutions. The mechanical properties also affected by chemical solutions, the mechanical tests show decreasing in the flexure strength, compression strength and hardness values for glass-reinforced polyester, HNO3 show more effective than anther chemical solutions, it is show decreasing in compression strength by 23% and in hardness by 22%, while the flexure strength reduced by 60%. | ||
