Abstract

1. Способ синтеза ароматических полиамидов в производстве высокопрочных арамидных нитей, включающий стадии растворения мономеров в растворителе и синтеза полимера, при этом процесс растворения мономеров и синтез полимеров осуществляется посредством перемешивания раствора высокоскоростным перемешивающим устройством, отличающийся тем, что перемешивание раствора осуществляют со скоростью вращения перемешивающего устройства в диапазоне от 2000 до 12000 об/мин.2. Способ по п. 1, отличающийся тем, что предпочтительно на стадии растворения мономеров максимальная скорость вращения перемешивающего устройства - порядка 10000-12000 об/мин, а на стадии этапа синтеза полимеров минимальная скорость вращения - порядка 2000-2500 об/мин.1. A method of synthesizing aromatic polyamides in the production of high-strength aramid yarns, comprising the steps of dissolving the monomers in a solvent and synthesizing a polymer, wherein the process of dissolving the monomers and synthesizing polymers is carried out by mixing the solution with a high-speed mixing device, characterized in that the solution is mixed at a rotational speed of the mixing device in the range from 2000 to 12000 rpm. 2. The method according to claim 1, characterized in that, preferably, at the stage of dissolution of the monomers, the maximum rotation speed of the mixing device is about 10,000-12,000 rpm, and at the stage of the stage of the synthesis of polymers, the minimum rotation speed is about 2000-2500 rpm.
