| Abstract: | Immersion corrosion test was carried out for polypropylene (PP) and rigid polyvinyl chloride (R-PVC) in itaconic acid aqueous solutions, simulating the service condition of itaconic acid production. By examing the variations in the weight, appearance, hardness, impact strength, composition and structure of specimens before and after immersion, the corrosion resistance of the two plastics was estimated. The results showed that both PP and R-PVC are corrosion resistant well to itaconic acid medk and may find application in the installations for itaconic acid production. |
