半芳香族聚间苯二甲酰己二胺的合成工艺研究
Study on the Synthesis Process of Semi-aromatic Poly(hexamethylene isophthalamide)
摘要
Abstract
This article uses hexamethylene diamine and isophthaloyl chloride as raw materials to prepare Polyisophthaloylhexanediamine(PA6I)by interface polymerization and solid-phase condensation method,and focuses on exploring its polymerization process.By analyzing the influence of interface polymerization type,concentration of isophthaloyl chloride and hexamethylene diamine,reaction temperature,type and dosage of acid binding agent,and interface polymerization area on its relative viscosity and molecular weight,the optimal polymerization process was obtained:with a monomer concentration of 0.2 mol/L for hexanediamine and isophthaloyl chloride;the reaction temperature is 70 ℃;the molar ratio of anhydrous sodium carbonate as a binding agent to the reaction monomer is 2:1.The relative viscosity of nylon 6I synthesized under these conditions can reach 1.78.关键词
