摘要
Abstract
The conditions of preparing the PPTA resin in solvent system were studied, including N, N - dimethyl acetamide, N - methyl pyrrolidone, lithium chloride and pyridine under low temperature. When the monomer concentration is 0. 26 - 0. 28mol/L, the monomer molar ration is 1. 024 - 1. 030, the volume fraction of NMP in mixed solvent is 6%, the amount of LiCl is 2. 6% - 2. 8% and the amount of Py is 0. 7 - 0. 8mol/L, the viscosity of PPTA can reach 4. 7 -4. 9. Compared with traditional process, the process increases the reaction rate and reduces demand on the solvent purity which is conductive to higher molecular weight of the PPTA.关键词
