Infrared spectral study of diphenylether polymers
- 47 Downloads
Infrared spectra of polymer, obtained by condensation of diphenylether with formaldehyde in sulphuric acid-alcohol medium are studied. Conclusions about the structure of the oligomer and the thermally treated products are made. A quantitative method for studying the dependence of the kinetics of polycondensation on the temperature and the quantity of the catalyst SnCl4, is developed.
