Abstract
The paper describes the solution of the problem of low chemical stability of resorcinol–formaldehyde resins in alkaline media. As was found using differential thermal analysis and 13C NMR, the temperature increase yielded the increase of the degree of the resin polymer network crosslinking. The relationship between the resorcinol–formaldehyde resins solidification temperature and their stability in alkaline media has been established for the first time: this will enable one to solve the problem of decontamination of large amounts of liquid media with high pH from 137Cs.
