摘要

A new method for activating the synthesis of high molecular weight polymer PIM-1 obtained in dimethyl sulfoxide is proposed and studied. A simple and technologically effective process of precipitation polyheterocyclization occurs at 60-80 degrees C for 2-5 h under constant exposure to ultrasound at a frequency of 37 kHz. This method allows one to synthesize the PIM-1 polymer with a molecular weight of up to 121 x 10(3) and a relatively low polydispersity index of 3.8. In addition to powder materials, microporous nanofibrous materials are obtained by electrospinning from polymer solutions. According to the Brunauer-Emmett-Teller method, the specific surface area of PIM-1 reaches 862 m(2)/g for powders and 362 m(2)/g for nanofibers.
