In this study, a commercial chain extender (Polyad PR 002) in concentrations of 0.5, 1.0, and 1.5% w/w was used as compatibilizer post-consumed PET/PA6 blends (25/75, 50/50 e 75/25) processed laboratory mixer. The degradation rate, phase miscibility, chemical interaction, crystallization, melting behavior, well the thermal stability mixtures, were analyzed by torque rheometry, scanning electron...
