Innovative polypropylene based blends by in situ polymerization of a polyimide dispersed phase by reactive extrusion

Charlotte Dubois et al.

Summary: Polypropylene/polyimide (PP/PI) blends were synthesized by reactive extrusion with the in situ polymerization of the polyimide phase. The in situ approach demonstrated clear advantages over the more classical dispersion process. The blends exhibited improved mechanical properties and thermal stability, with significant impact on rheological behavior.

Carbonation of epoxidized soybean oil in supercritical CO2 assisted by imidazole-based organocatalysts

Juan Catala et al.

Summary: The production of cyclic carbonates from epoxidized vegetable oils allows for the introduction of CO2 into renewable and highly functional resources, resulting in high-value products that can serve as precursors for chemicals such as non-isocyanate polyurethanes (NIPUs). The use of supercritical CO2 as the reaction medium improves yields and eliminates the need for organic solvents. The study focuses on the carbonation of triglycerides using a new class of bifunctional imidazole-based catalysts and quaternary ammonium salts. By optimizing the operating conditions and comparing reaction performance, the kinetic rate of ESBO supercritical carbonation was found to be the highest at 120℃, 125 bar of CO2 pressure, and a 7.5 mol% IOC catalyst ratio.

TPV Foaming by CO2 Extrusion: Processing and Modelling

Benoit Rainglet et al.

Summary: This work focuses on the extrusion foaming under CO2 of commercial TPV and how the process influences the final morphology of the foam. Moreover, numerical modelling of the cell growth of the extrusion foaming is developed. The results show how a precise control on the various parameters can provide a homogeneous foam with low density, and propose a model to predict the influence of CO2 on the flow. The study also presents a global model to simulate the extrusion process and foaming inside and outside the die.

Thermomorphic Polyethylene-Supported Organocatalysts for the Valorization of Vegetable Oils and CO2

Ayman Akhdar et al.

Summary: A range of thermomorphic polyethylene-supported organocatalysts were prepared with good yields and high functionality, and studied for the ring opening of epoxidized methyl oleate with CO2. The optimized conditions were applied to a range of epoxidized fatty acids, showing good yields of the corresponding carbonates. Catalyst recycling study demonstrated no significant loss of activity, making fatty carbonates important intermediates for non-isocyanate polyurethanes (NIPUs) preparation.

Hybrid Chemomechanical Plastics Recycling: Solvent-free, High-Speed Reactive Extrusion of Low-Density Polyethylene.

Shawn Martey et al.

Summary: A study investigates a hybrid chemomechanical approach involving reactive twin-screw extrusion (TSE) to tailor the molecular weight and chain structure of reclaimed LDPE, evaluating two types of zeolite catalysts at various loading levels over a range of processing conditions. Results show that using different zeolite catalysts can alter specific properties of LDPE, potentially providing a low-cost, simple method for repurposing LDPE-based flexible packaging.

Sequence Control from Mixtures: Switchable Polymerization Catalysis and Future Materials Applications

Arron C. Deacy et al.

Summary: The article discusses an efficient and broadly applicable method for producing copolymers using switchable polymerization catalysis, which utilizes a single catalyst switched between different catalytic cycles to prepare block sequence selective copolymers from monomer mixtures. It presents the principles of this catalysis, catalyst design criteria, selectivity and structural copolymer characterization tools, as well as the properties of resulting copolymers.

Cycloaddition of CO2 to epoxides by highly nucleophilic 4-aminopyridines: establishing a relationship between carbon basicity and catalytic performance by experimental and DFT investigations

Wuttichai Natongchai et al.

Summary: The study discovered that highly nucleophilic 3,4-diaminopyridines can serve as effective catalysts for the cycloaddition of CO2 to epoxides, enhancing catalytic activity and promoting crucial reaction steps. Additionally, the research also demonstrated that the nucleophilic scaffold of 3,4-diaminopyridines can be used as a recyclable heterogeneous catalyst supported on polystyrene.
