Summary: SAN and ABS, as food contact materials, contain oligomers such as trimers which are the main extractable substances. Migration testing showed that the migration of trimers into 50% ethanol as a food simulant overestimated the actual migration into milk.

Summary: In this study, acrylonitrile-styrene-acrylate copolymer (ASA) particles were synthesized with different microstructure via emulsion polymerization for toughening poly(styrene-co-acrylonitrile) (SAN) resin. The optimum toughening efficiency was achieved when ASA particles had a complete core-shell structure with a shell composition similar to the SAN matrix. Adjusting the microstructure of the particles, including morphology, composition, and size, improved the notched impact strength of the resin without sacrificing tensile strength. The toughening mechanism was attributed to the crazings and cavitation of particles observed on impact-fractured surfaces.

Summary: This study investigated the relationship between montmorillonite (MMT) content, rotational viscosity, and colloidal index of sodium montmorillonite (Na-MMT) and the dosage of sodium agent, reaction time, reaction temperature, and stirring time. The Na-MMT was modified with octadecyl trimethyl ammonium chloride (OTAC) under optimal conditions. The modified MMT products were characterized using various analytical techniques. The results showed that the optimal Na-MMT was obtained at specific conditions and that OTAC modification improved its properties.

Summary: This study focuses on spelt husk and nanoclay-modified polypropylene composites for injection-moulding applications. The addition of nanoclay fillers has insignificant influence on the viscosity of the composites, but it improves the tensile and flexural modules and thermal stability. Natural materials like agricultural residues and clay minerals show potential in enhancing the stiffness and thermal properties of polypropylene composites.

Summary: This study investigates the feasibility of using acrylonitrile butadiene styrene and wood sawdust to prepare wood polymer composites. The results show that the mechanical properties and viscoelastic properties of the composites are significantly affected by the wood sawdust content. The findings suggest that wood polymer composites could be used as alternative structural materials to virgin polymer.

Summary: The study focused on loading expandable graphite (EG) into acrylonitrile-butadiene-styrene (ABS) terpolymer and analyzing the performance of the composites through various tests. Results showed that with an increase in EG content, certain mechanical properties of ABS improved, while elongation and impact strength exhibited a decreasing trend. The 15% and 20% EG-containing ABS composites were identified as the most suitable candidates among the prepared composites.

Summary: Combining SIS polymer with CR modification can enhance the high-temperature performance and reduce the low-temperature stiffness of bitumen. This combined modification method shows satisfactory performance under low-and high-temperature conditions and provides a more cost-effective solution compared to using SIS polymer alone.

Summary: The antifouling properties of a poly(acrylonitrile-styrene) copolymer incorporated with silver nanoparticles (AgNPs) were studied in a microfiltration membrane process. It was found that the use of AgNPs enhanced the antifouling properties of the copolymer membrane. SAXS analysis indicated that this enhancement was related to the structure of the AgNPs in the casting solution. The results suggest that the poly(acrylonitrile-styrene) copolymer membranes containing AgNPs have promising industrial wastewater treatment applications.

Summary: To address the environmental damage caused by untreated plastics, an acrylonitrile butadiene styrene (ABS)/poplar composite with excellent properties was prepared by a novel one-step method. The composite exhibited improved tensile strength, flexural strength, water resistance, and thermal stability compared to poplar and plywood. This poplar-ABS composite shows great promise for versatile applications in furniture and construction, offering the potential to replace commercial plastics.

Summary: Eucalyptus/polyvinyl chloride (PVC) composites with different contents of acrylonitrile styrene acrylate copolymer (ASA) were prepared by extrusion molding. The effects of ASA content on the mechanical properties, water absorption properties, and thermal stability of the composites were studied. The addition of ASA improved the mechanical properties, heat resistance, and interfacial compatibility of the composites, while reducing water absorption. The best mechanical properties and heat resistance were achieved when the ASA content was 10 wt%, with the lowest water absorption in 24 hours.
