Summary: In this study, a novel room temperature curable epoxy resin was developed by blending with different proportions of hydroxyl terminated poly (etheretherketone)s (PEEKTOH) as a thermoplastic toughening agent, which effectively reduced the brittleness and improved toughness. The experiments showed that the lap shear strength of the toughened adhesive improved by about 19%, and the fracture toughness of the cured blends increased significantly.

Summary: In this study, the brittleness of epoxy resin (EP) was successfully modified by adding high-performance thermoplastic poly(ether nitrile ketone) containing phthalazinone structures (PPENK). The influence of different PPENK contents on the mechanical, thermal, and low-temperature properties of EP was comprehensively investigated, and the binary blend of PPENK/EP showed excellent properties due to homogeneous mixing and good interaction. The presence of PPENK significantly improved the mechanical properties of EP and enhanced the thermal and low-temperature properties of the blends.

Summary: Three novel aromatic diamines with varying lengths of oxyethylene sequences were synthesized and polymerized to create twelve poly(ether amide)s. The presence of polydisperse PEO sequences in the polymer backbone was found to significantly impact the crystallinity, flexibility, solubility, and thermal properties of the polymers. This study highlights the importance of the polydispersity of PEO segments within the structural units on the properties of the resulting materials.

Summary: This study describes a simple approach for copper-promoted S-arylation reactions using triarylbismuths or triarylantimonys as arylating reagents. These reactions can be performed under mild conditions and exhibit remarkable functional group tolerance and chemoselectivity. Good to excellent yields were achieved in over 49 examples, leading to the successful synthesis of corresponding 2-arylthiopyridine 1-oxide derivatives and arylthioanilines/phenols.

Summary: Transition metals and metal halides have been efficiently used as catalysts for the hydrosilylation of carbonyl compounds to synthesize silyl ethers. The use of dicarbonyls or hydroxy ketones with dihydrosilanes has led to the production of poly(silyl ether)s (PSE)s. Inexpensive and metal-free catalysts have gained interest in the synthetic approach for PSEs. Furthermore, metal-free catalysts have found practical applications in polymer chemistry.
