Reaction of unactivated alkenes affords various fluoroalkyl-containing alkyl sulfonyl fluorides with good functional group tolerance under mild conditions.
Abstract The compatibility of nylon 11/polyethylene (PE) alloys on addition reactive maleated ethylene‐propylene‐diene copolymer (EPDM‐ graft ‐MAH) was investigated by differential scanning calorimetry, morphological observations and rheology. decrease in the volume melting temperature 11 PE with increasing compatibilizer suggests that EPDM‐ ‐MAH affects crystalline behavior PE. decreased particle size dispersed phase also confirmed improvement compatibility. rheological revealed enhanced...
Abstract BACKGROUND Membrane technology has attracted increasing interest in the field of separation and purification. Unfortunately, conventional membrane materials are usually derived from non‐renewable fossil resources that difficult to degrade at end their life. In this work, as a sustainable alternative polymer membrane, biobased ploy (L‐lactic acid) (PLLA) hybrid was successfully fabricated through incorporation modified natural halloysite nanotubes (HNTs). RESULTS The PLLA/HNT...
Polybenzoxazine foam was successfully prepared using phenolic resin as modifier and catalyst. The structural properties, curing behavior, thermal stability, cellular structure, mechanical properties flame retardancy of the were characterized by Fourier transform infrared (FTIR) spectrometry, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), electron microscopy (SEM), compression tests, limiting oxygen index (LOI) tests cone test, respectively. experimental results...
A direct electrophilic difluoroalkylthiolation reaction of indole derivatives and other electron-rich heterocycles using methyl 2,2-difluoro-2-(chlorsulfonyl)acetate (ClSO2CF2COOMe) derived from Chen's reagent (FSO2CF2COOMe) is described. The ester group in the product can be further utilized subsequent versatile transformations. reactions provide good yields corresponding products exhibit high functional compatibility. It expected to serve as an alternative practical protocol for various...
