The majority of materials used for short-term and disposable packaging application are non-biodegradable which are not satisfying the demands in environmental safety and sustainability. Biodegradable polymers are an alternative for these nonbiodegradable materials. The biodegradable polymeric materials can degrade in a reasonable time period without causing environmental problems. However, biodegradable polymers possess some limitations such as comparatively high cost, insufficient mechanical performances, and inferior thermal stability to extend their widespread application in packaging industry. To overcome these limitations, one of the most commonly used strategies is melt blending of dissimilar biodegradable polymers. Unfortunately, most of the biodegradable polymer blends exhibit insufficient performance because they are thermodynamically immiscible as well as exhibit poor compatibility between the blended components. It has been established that the compatibilization is a well-known strategy to improve the performances of the immiscible biodegradable polymer blends by enhancing the adhesion between the phases. As a result, recent studies focus on various compatibilizers to enhance the performances of the resulting biodegradable polymer blends. This review summarizes the recent developments on a variety of biodegradable polymer blends compatibilized by melt processing with a main focus of ex situ and in situ compatibilization strategies.

“…Based on these aspects, in situ reactive processing can be introduced and applied for hybrid composite processing, allowing the possibility of increasing the interfacial adhesion with a cost-effectiveness in terms of the manufacturing technique [ 10 ]. Some of the current in situ compatibilizers used for each biopolymer blends have been investigated, such as Methylene diphenyl diisocyanate (MDI) used in Poly(lactic acid)/Polybutylene succinate [ 18 ] and Poly( l -lactic acid)/Polycaprolactone [ 19 ], Dicumyl peroxide (DCP) used in Poly( l -lactic acid)/Polybutylene succinate [ 20 ] and PHB/Polybutylene succinate [ 21 ], Joncryl used in Poly(lactic acid)/PBSA [ 22 ], Poly(lactic acid)/Polypropylene carbonate [ 23 ] and Poly( l -lactic acid)/PBAT [ 24 ], PLA-g-GMA (glycidyl methacrylate grafted Poly(lactic acid) used in PLA/Starch [ 25 ], PLA-g-MA (Maleic anhydride-grafted Poly(lactic acid)) used in Poly(lactic acid)/Polycaprolactone [ 26 ], Poly(lactic acid)/Starch [ 27 ] and Poly( l -lactic acid)/Polybutylene adipate terephthalate [ 28 ]. From our previous work, different types of reactive agents including multifunctional epoxide-based reactive terpolymer (CEGMA, EAGMA) and maleic anhydride-based reactive terpolymer (EAMAH) were introduced as in situ reactive compatibilizer in the processing of PLA biocomposites [ 10 ].…”

Hybrid composites of fillers and/or fibers reinforced polymer was generally produced by masterbatch dilution technique. In this work, the simplified preparation was introduced for the large volume production of 30 wt % short-fiber and talcum reinforced polymer hybrid composite by direct feeding into twin-screw extruder. Multifunctional epoxide-based terpolymer and/or maleic anhydride were selected as in situ reactive compatibilizers. The influence of fiber and talcum ratios and in situ reactive compatibilizers on mechanical, dynamic mechanical, morphological and thermal properties of hybrid composites were investigated. The morphological results showed the strong interfacial adhesion between fiber or talcum and Poly(lactic acid) (PLA) matrix due to a better compatibility by reaction of in situ compatibilizer. The reactive PLA hybrid composite showed the higher tensile strength and the elongation at break than non-compatibilized hybrid composite without sacrificing the tensile modulus. Upon increasing the talcum contents, the modulus and storage modulus of hybrid composites were also increased while the tensile strength and elongation at break were slightly decreased compared to PLA/fiber composite. Talcum was able to induce the crystallization of PLA hybrid composites.

“…PPC has been blended with other biobased thermoplastics such as cellulose acetate butyrate (CAB), poly(butylene succinate) (PBS), poly(ester‐amide) (PEA), poly(lactic acid) (PLA), poly(propylene succinate) (PPS), polyhydroxybutyrate (PHB), and poly(hydroxybutyrate‐co‐hydroxyvalerate) (PHBV) . The general consensus of blending PPC with other, either partially or completely miscible polymers was that they were able to improve the thermal and mechanical properties of PPC.…”

“…The general consensus of blending PPC with other, either partially or completely miscible polymers was that they were able to improve the thermal and mechanical properties of PPC. For the blends that were immiscible with one another, additives were incorporated to improve the compatibility between the two phases . Therefore, changes to the thermal transitions, thermal stability, morphological, and mechanical properties were observed for blends that exhibited some miscibility with or without a compatibilizer.…”

Poly(propylene carbonate) (PPC), a CO 2 -based bioplastic and poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) were melt blended followed by injection molding. Fourier transform infrared spectroscopy detected an interaction between the macromolecules from the reduction in the OH peak and a shift in the C@O peak. The onset degradation temperature of the polymer blends was improved by 5% and 19% in comparison to PHBV and PPC, respectively. Blending PPC with PHBV reduced the melting and crystallization temperatures and crystallinity of the latter as observed through differential scanning calorimetry. The amorphous nature of PPC affected the thermal properties of PHBV by hindering the spherulitic growth and diluting the crystalline region. Scanning electron micrographs presented a uniform dispersion and morphology of the blends, which lead to balanced mechanical properties. Incorporating PHBV, a stiff semi-crystalline polymer improved the dimensional stability of PPC by restricting the motion of its polymer chains.
