Synthesis of hyperbranched polyglycidylnitrates

摘要

Hyperbranched polyglycidylnitrates with molecular weights (M_n) from 1500 to 5300 were obtained for the first time. A method for nitration of hyperbranched polyglycidols prepared both with catiomc and anionic polymerization has been developed. This method allows for controlled substitution of OH-groups for ONO_2-groups without degradation of the chains of the starting polymers. The structure of the synthesized substances was proved by means of IR and NMR spectroscopy. Based on the data of ~1H,~(13)C and 2D ~1H/~(13)C HSQC NMR spectra, the structure of obtained compounds was determined.
