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.

摘要:A method for producing elliptical, needle-shaped, or rod-shaped polymer particles satisfying (1)-(3) below includes a step in which a synthesis solution including water, a mixed solvent of a hydrophilic organic solvent and a hydrophobic organic solvent, a polymeric stabilizer, a polymerization initiator, and an unsaturated monomer is heated, and, at least after the heating has started, the pH of the synthesis solution is adjusted to 5-9 inclusive to perform solution polymerization: (1) the average (L AV ) length (L) in a two-dimensional projection diagram obtained by irradiating the particles with light from a direction orthogonal to the longitudinal direction is 0.1-80 μm; (2) the average (D AV ) breadth (D) in the two-dimensional projection diagram obtained by irradiating the particles with light from the direction orthogonal to the longitudinal direction is 0.05-40 μm; and (3) the average (P AV ) aspect ratio (L/D) calculated from the length (L) and the breadth (D) is 1.5-30.
