Summary: The study focused on the reinforcement effect of PIBOMA on rubber compounds, showing that PIBOMA can increase the torque increase values and maintain its reinforcing effect up to 180 degrees C. For rubber compositions containing 20 phr of PIBOMA, both tensile strength and elongation at break decreased with increasing PIBOMA molecular weight.

Summary: For the first time, styrene-butadiene-glycidyl methacrylate (SBG) was incorporated into the recovered acrylonitrile-butadiene-styrene (rABS) and recycled high impact polystyrene (rHIPS) system by melt blending to increase effectiveness. The epoxy groups in SBG react with the butadiene aging groups in rABS/rHIPS, resulting in the formation of ester groups, which repairs broken molecular chains, improves phase compatibility, and enhances mechanical properties of the blends. Adding SBG significantly improves the molecular weight, impact strength, tensile strength, flexural strength, storage modulus, loss modulus, and complex viscosity of the blends. When SBG content is 8 wt%, the notch impact strength of the blends increases by 108% compared to rABS/rHIPS. Furthermore, the interface between the polybutadiene (PB) phase and styrene-acrylonitrile copolymer (SAN) phase becomes less distinct, improving the compatibility and enabling high-value recovery of rABS/rHIPS.

Summary: A novel compatibilizer, sulfonate imidazolium polyurethane (IPU), and multi-component epoxy chain extender (ADR) were used to improve the performance of poly(lactic acid)/poly(butylene terephthalate adipate) (PLA/PBAT) composites, by enhancing interfacial compatibilization and dispersion of carbon nanotubes (CNTs) within the composites. Various characterization techniques were employed to evaluate the thermal stability, rheological behavior, morphology, and mechanical properties of the composites. The results showed that the introduction of IPU and modified CNTs led to improved interfacial compatibilization, adhesion, and mechanical properties of the PLA/PBAT composites.

Summary: This study investigated the reactive modification of acrylonitrile-butadiene-styrene (ABS) with glycidyl methacrylate (GMA) in a melt mixing process. The graft ratio of GMA in ABS increased with increasing GMA concentration and reached a maximum value within a certain range of mixing time. The effect of mixer RPM on graft rate was insignificant, while the graft ratio decreased with increasing processing temperature. Furthermore, blending GMA-grafted ABS with poly(lactic acid) (PLA) resulted in a remarkable reduction in domain size as the complex viscosity increased.

Summary: Reactive interfacial compatibilization is found to be an effective method for preparing super-tough poly (lactic acid) (PLA) materials through introducing a reactive group into toughening agents that can react with PLA. Super-tough PLA materials can be obtained by reactively blending with a series of fully bio-based polyesters (PBSePM) and hexamethylene diisocyanate (HDI). The maximum impact strength of 83 kJ m(-2) is achieved with PBSePM containing 20% diethyl malate moiety, demonstrating a highly efficient toughening effect with the addition of only 15 wt% PBSePM20.

Summary: In this study, super toughened PLA-based blends were successfully prepared by melt blending PLA with EVA and compatibilizing with E-MA-GMA. The addition of E-MA-GMA promoted phase adhesion and increased interface thickness, resulting in a super-toughened blend with incomplete fracture behavior during impact tests. The maximum impact strength of 77.6 kJ/m(2) was achieved with 12 wt% E-MA-GMA in the ternary blend, showing a 27.7 times improvement over neat PLA. Rheological and micromorphology analysis demonstrated enhanced viscosity and reduced crystallinity in the ternary blends.

Summary: The effects of different molecular weight (Mw) of PGMA on PLA/PBAT blends were investigated. It was found that Mw played a crucial role in the dispersion and mechanical properties of the blends. Low Mw PGMA improved the interfacial adhesion between PLA and PBAT, resulting in increased tensile strength and elongation at break of the blends. On the other hand, high Mw PGMA led to non-uniform dispersion of PBAT in the PLA matrix, resulting in decreased mechanical properties.

Summary: Terephthalic acid reformed Al/Zn metal organic nanoflake functionalized with trie-thylamine (T-AlZn) exhibits remarkable performance in removing trace lead (II) ions (Pb2+), with an adsorption equilibrium reached within 35 min and a removal rate ≥ 97%. After four regenerations, the decline in removal rates of T-AlZn for Pb2+ is only 16.73%. The adsorption of T-AlZn for Pb2+ follows the Langmuir isotherms model and pseudo-second-order dynamics model, with the utmost adsorption competence of 215.27 mg g-1. T-AlZn adsorbent shows a bright prospect in the adsorption for Pb2+ and is a considerable candidate in the disposal of industrial sewage.
