Novel Polycondensation System for the Synthesis of Polyamides and PolyestersNovel polycondensation reaction has been developed for the synthesis of polyamides and polyesters under mild conditions. Phosphorylation reaction using triphenyl phosphine or triphenyl phosphine dichloride could initiate a direct polycondensation reaction under such mild conditions as ambient temperature to form either polyamides or polyesters.作者: PRO 時間: 2025-3-22 16:38

Miller and Bandermann have encountered induction periods; Du Pont does not. To get better agreement, we need to purify monomer, solvents, initiators, and catalyst the same way and check each other’s experiments. Absolute rates should be compared.作者: Semblance 時間: 2025-3-22 20:22
