Abstract

L'invention décrit des agents de durcissement d'un polyuréthanne et leurs applications. On a trouvé que des esters salicyliques sont des agents convenables de blocage de polyisocyanate, permettant de préparer des grains de propergol liés par du polyuréthanne à base de polybutadiène terminé par des groupes hydroxyles et présentant une durée prolongee de conservation possible en pots aux températures ambiantes. Le déblocage (dissociation) se produit facilement aux températures normales de durcissement du propergol, ce qui permet des vitesses normales de durcissement.
