摘要:Aromatic sulfides including diarylsulfides and poly(arylene sulfides) are produced in a novel synthesis in high yield under moderate conditions by heating an aromatic disulfide in the presence of aromatic halide, in which the halide is chloride, bromide or iodide; the diaryl sulfides are useful precursors and starting materials for a range of compounds and the poly(arylene sulfides) are important high temperature engineering thermoplastics.

摘要:The present invention relates to covalent network-based polymers derived from imine and disulphide based crosslinkers with the epoxy. The recyclability of the high-cost fibres is achieved by the synthesis of epoxy vitrimers based on dynamic imine and imine-disulphide bonds. Schiff base chemistry and condensation reaction are used to prepare the crosslinkers with imine linkages as well as imine-disulphide linkages. Various aromatic carbonyl compounds like divanillin, terepthaldehyde, vanillin, 4-hydroxy benzaldehyde, isatin etc. are used for the reaction with various aliphatic and aromatic amines like IPDA, 2-AFD, 4-AFD etc. The prepared epoxy vitrimers showed comparable thermal, mechanical and thermomechanical properties with the conventional DGEBA epoxy-amine system. The carbon/glass fiber-reinforced composite with the vitrimers showed superior mechanical properties beneficial for many engineering applications. The recycling of the vitrimers and composites can be achieved by simple immersion in a suitable solvent system with stirring or agitation at ambient temperature (30-60ºC) conditions. The fibers were easily recovered without losing their morphology, strength and structural integrity. With this invention, wastage of reinforcement carbon fibers and glass fibers can be minimized and the recovered fibers can be used for other applications with a circular economy approach.
