“…The first one is between 340 and 400°C and may be due to the maximum decomposition of aliphatic copolyester adipic acid and 1,4‐butanediol. The second one occurs at around 600°C, and it is explained by decomposition of aromatic copolyester terephtalic acid …”

Biodegradable poly(butylene adipate-co-terephthalate) (PBAT) films incorporated with different levels of the antimicrobial peptide nisin were developed by melt processing. Structural, morphological, thermal, mechanical, and antimicrobial properties of the films were determined. The X-ray diffraction patterns exhibited decreasing levels of intensity at 2h values as the concentration of nisin increased. Scanning electron microscopy showed a heterogeneous morphology when higher amounts of nisin were incorporated. The antimicrobial films tested presented no significant differences in the melting temperature (123-1258C), and the crystallization temperature ranged from 69 to 758C. The addition of nisin caused no significant modification in tensile strength values. However, results of Young's modulus and deformation at break differed significantly among samples. Active films demonstrated inhibition against the Gram-positive bacterium Listeria monocytogenes. These results demonstrated that PBAT/nisin films produced by melt processing present a great potential for use as active food packaging materials aiming enhanced food safety.

Poly(lactic acid) (PLA)/poly(butylene adipate-co-terephthalate) (PBAT) blends and their composite were prepared by melt compounding. Maleic anhydride grafted PLA (PLA-g-MA) was used as a compatibilizer. With the addition of PBAT into PLA, elongation at break and impact strength increased but tensile strength and modulus decreased. Incorporating PLA-g-MA into PLA/PBAT blend improved the mechanical properties of the blend. Tensile properties of blown film prepared from the compatibilized PLA/PBAT blend were better than those of the uncompatibilized PLA/PBAT blend. Incorporating CaCO 3 resulted in increased tensile strength and modulus of the film prepared from the compatibilized blend.

“…Figure 7 shows that PVC and the blends exhibit similar thermal behavior: there are two degradation steps in the temperature ranges 240-360°C and 440-490°C. The first degradation step corresponds to dehydrochlorination of the PVC chain, and the second results in the thermal decomposition of the dehydrochlorinated PVC, which has conjugated double bonds [17,21]. The profiles shows that the weight loss of PVC during the first stage begins at a higher temperature than it does for the blended PVC.…”

“…However, when the PMA composition increases to a certain dosage (1.2 wt%), the blendings become elastic due to containing enough flexible polyacrylate chains, resulting in decrement in the mechanical properties of the blendings [19]. Moreover, increment of the mechanical properties may be due to hydrogen bonding between the hydrogen-bound electronegative chloro-(PVC) and carbonyl-containing polymers, which reduced the sliding of the PVC chains when an external force is applied to the resin, resulting in the enhanced tensile strength of the blends [17].…”

“…Epoxidized natural rubber and PMA were blended with PVC to improve the mechanical properties of the blend [16]. Butylene adipate-co-terephthalate also plays an important role in enhancing the mechanical properties of PVC blends [17]. According to the above reports, these polymers are compatible with PVC, and including them improves the mechanical properties of the blends, which can be explained by invoking hydrogen bonding between hydrogen-bound electronegative chloro-(PVC) and carbonylcontaining polymers.…”

Star-shaped poly(methyl acrylate) (PMA) was synthesized using tri(2-bromopropionate) glyceride as the initiator and methyl acrylate as the monomer via atom transfer radical polymerization (ATRP). The structures of tri(2-bromopropionate) glyceride and PMA were characterized by IR, GC-MS, 1 H NMR, and 13 C NMR. The reinforcing effects of this star-shaped PMA on polyvinylchloride (PVC) in various PMA/PVC blends were evaluated. The results indicated that a blend containing 1% star-shaped PMA exhibits an 18% increase in the elastic modulus and a 10% increase in tensile strength compared to PVC. Moreover, the impact resistance of the blend was 30% higher than that for PVC. The blend also exhibited high thermal stability. SEM images showed that the star-shaped PMA and PVC are highly compatible when blended, which causes the enhanced elasticity of the blend.
