FIELD: polymer production. ^ SUBSTANCE: polyglycidylazide with terminal azide groups is prepared by azidizing of intermediate polyepichlorohydrin nitrate with sodium azide in dimethylformamide at 90-95. Polyepichlorohydrin nitrate, in turn, is obtained by nitration of polyepichlorohydrin with mixture of concentrated nitric and sulfuric acids in chloroform at 30-35 for three hours. ^ EFFECT: simplified process. ^ 2 ex |
