Investigation of the butyl rubber-toluene system by the paramagnetic probe method
- 30 Downloads
The paramagnetic probe method permits an investigation of the microstructure and mutual solubility in two component polymer-solvent systems.
In the system butyl rubber-toluene, containing 40, 50, and 55% of the polymer, microstratification was detected at the temperatures 225, 227, and 235°K, respectively, as a result of which the radical probe is localized in portions with an increased content of the solvent.
