POLYMERS WITH TERMINAL AZIDE FUNCTIONS, THEIR OBTAINING; SOLID PROPERGOLS OBTAINED FROM SAID POLYMERS

摘要

The subject of the present invention is: - polymers with an azide terminal function of formula (IV) - obtaining such polymers from + a hydroxytelechelic polymer of formula (I): OH-P-OH; + an azidoalcohol of formula (II): HO-R1-N3, and + of a diisocyanate of formula (III): O = C = N-R2-N = C = O - solid propellants, capable of be obtained from said polymers. Said propellants may contain any type of energy charges, including energy charges with intrinsic acidity.
