Title: Synthesis of polyamide having high degree of polymerization
Inventor: MIYAWAKI YASUFUMI
IPC: C08G69/00
Filed: 1987-11-30
Abstract: PURPOSE:To produce a polyamide having a high degree of polymerization easily, by subjecting a primary diamide and a dihalide to condensation polymerization in a solution obtained by blending an aprotic polar solvent with Na or NaH. CONSTITUTION:A primary diamide of formula I (wherein R1 is a divalent alkyl, an aromatic ring or a group containing the both) and a dihalide of formula II (wherein R2 is the same as R1; and X is halogen) are subjected to condensation polymerization in a solution obtained by blending dimethyl sulfoxide (DMSO) or dimethyl formamide (DMF) with Na or NaH to synthesize a polyamide having a high degree of polymerization, for example, by the reaction of formula III. According to the reaction, sodium halide that is a by-product deposits as a precipitate, and cannot participate in the reaction system, so that the polyamidation proceeds smoothly. The primary amide cannot react with the alkyl halide merely by mixing them. The reaction can be promoted easily by the formation of an N anion wherein a metal is coordinated on the N atom. of the amide.
