Interfacial polycondensation of diphenolic acid and isophthaloyl chloride

Abstract

Interfacial polycondensation of diphenolic acid (DPA) and isophthaloyl chloride (IPC) in various solvent/water systems was investigated with tetrabutyl ammonium chloride as a phase transfer catalyst. It was found that a large mass of capsules were formed at the beginning of the reaction for all solvents examined but the capsule morphology and reaction results depended on the solvents. It is believed that the capsule shells make up of the reaction zone and a mechanism of the interfacial polycondensation is proposed accordingly. The effect of the solvents on the reaction was interpreted from the interaction between the polymer and the solvent according to the mechanism. The reaction conditions were optimized, and poly(DPA-IPC) with high intrinsic viscosity was prepared in high yield under the optimal condition. It is an amorphous polymer with glass transition temperature of about 1608C.

High‐performance soluble copolyarylate based on phenolphthalein: synthesis, characterization and properties

“…All polymers were prepared via interfacial polymerization [25][26][27] using BTEAC as the phase-transfer catalyst. Co-PARs prepared here were named as PPx, in which x represents the molar percentage of PP component.…”

Layer by layer deposition of polyethylenimine and bio-based polyphosphate on ammonium polyphosphate: A novel hybrid for simultaneously improving the flame retardancy and toughness of polylactic acid

“…14 On the basis of the discussion mentioned above. Herein, a novel bio-based polyelectrolyte (BPE) was designed and synthesized in two steps using diphenolic acid (DPA) as raw material, which is a plant-derived compound widely used for synthesis of polyesters 15 and polycarbonates, 16,17 etc. The as-synthesized BPE exhibits a good char forming ability and has good compatibility with the PLA matrix.…”
