Plasticized cellulose acetate (pCA) using biobased triacetin (TA) as a plasticizer and poly(butylene adipate-co-terephthalate) (PBAT) were blended at three weight fractions (ranging from 25/75 to 75/25), two organic peroxides, 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane (Lup) dicumyl peroxide (DCP), compatibilizing agents. The compatibilizers, compounds, should work achieve the miscibility of both polymers, resulting in material with an appropriate stiffness–toughness balance for single-use sustainable packaging applications. Scanning electron microscopy (SEM) images showed that PBAT/pCA blend ratios completely immiscible within range studied this work, despite solubility parameters indicating partial between them. Rheological properties differential scanning calorimetry changes analyzed blends, influenced by type (Lup or DCP), quantity (0.025–0.05 phr) ratio. DCP exhibited better compatibilization, affecting 75/25 blends more than 50/50 blends. rheological modified increase storage modulus complex viscosity comparison unmodified pCA samples, confirming cross-linking structures.

Abstract Herein, the effects of varied concentrations an organic peroxide and maleic anhydride (MA) on grafting percentage as well amount gel content, rheological, thermal properties MA‐grafted‐poly(butylene succinate‐co‐adipate) (PBSA) were analyzed. The was performed by melt extrusion processing. MA onto PBSA polymer chains successfully confirmed through Fourier transform infrared spectroscopy, MA‐grafting quantified back titration. Increasing initiator content increased peak intensity (at 1780 cm −1 ) associated with grafted saturated moieties backbone. Higher directly influenced percentage, reaching to maximum degree 2.48%. A greater produced more radicals chain, promoting crosslinking reactions, resulting in a higher complex viscosity. This and, thus, Additionally, increase affected stability MA‐grafted‐PBSA where decomposition temperature ⁓7°C, result improved effect. reduced chain regularity (MA‐g‐PBSA); therefore, crystallinity decreased. Gaining insight into impact can aid developing composites or blends enhanced miscibility performance.
