摘要：

This work reports the thermal and structural changes promoted by Buriti (Mauritia flexuosa L.) oil incorporation into polystyrene (PS) and poly(methyl methacrylate) (PMMA) matrices. Buriti oil, which was used due to its high beta-carotene content has a good thermal stability and can provide some stability to PS and PMMA as it was shown by TG and TMA data. DSC results showed that both PMMA and PS-based materials were plasticized by the oil and demonstrated that they are immiscible materials. SEM images depict the materials' morphology.
