At molar ratio of monomeric initiator:macrodiisocyanate = 1:2 polyazoinitiators of structure RXR, where R - oligomeric block, Х - azoinitiator block have been synthesized. At molar ratio of monomeric initiator:macrodiisocyanate = 1:1 polyazoinitiators of structure (RX)nR have been synthesized. The structures of initial mixtures of reagents and end products by IR- and UV-spectroscopy have been determined. Product Description popup.authors popup.nrat_date 2020-04-02 Close
