Study on the Effect of Some Reactive Dyes on Stability during the Thermooxidation of the Isotactic Polypropylene

摘要

This work presents a study on the interaction that a phenolic hindered antioxidant (Irganox-1076) and new reactive dyes derived form 3H-aza-1-oxa-2H-thioxo-5,8-phenalendisulphonic acids, have upon izopolipropylene thermooxidation. The study was performed by chemiluminescence technique (CL). Synergetic effects were observed between reactive dyes used and phenolic antioxidant in thermooxidation protection of the polymer.
