Phase equilibria in the system poly(butadiene-CO-acrylonitrile) – lithium perchlorate

Phase equilibria in the system poly(butadiene-co-acrylonitrile) (40:60) – LiClO4, had been studied by means of X-ray, optical microscopy and IR spectroscopy at 25-90°C. The results obtained demonstrate that the limit of the homogen ious area of the macromolecular ionic solution increase with temperature from 2.12 to 2.77 mol/dm. It was established that the temperature increase up to 90°C did not reveal the thermal destruction of the polymer matrix. The change of the individual poly(butadiene-co-acrylonitrile) (40:60) to the large scale produced butadiene-nitrile rubber with the same macromolecular backbone nature containing emulsifier (calcium stearate) and stabilizer (agidol-2) additives does not have remarkable influence on the phase equilibria in the system.
