Bioabsorbable compounds which include a polyalkylene oxide backbone with two or more isocyanate substituents are useful as one component adhesives. Absorbable compositions useful as a two component adhesive contain a) a polyethylene oxide having two or more amine substituents with b) a bioabsorbable diisocyanate compound, or alternatively contain a) a polyethylene oxide having two or more isocyanate substituents with b) a bioabsorbable diamine compound, or, alternatively contain a) a bioabsorbable diisocyanate compound and b) a bioabsorbable diamine compound.

L'invention porte sur des composés bioabsorbables à squelette d'oxyde de polyalkylène et à deux ou plus de deux substituants d'isocyanate, utilisables comme constituants d'adhésifs, et sur des compositions absorbables utilisables comme adhésifs à deux composants comprenant: a) un oxyde de polyéthylène à deux ou plus de deux substituants d'amine + b) un composé bioabsorbable de diisocyanate, ou en variante a') un oxyde de polyéthylène à deux ou plus de deux substituants d'isocyanate + b') un composé bioabsorbable de diamine, ou en autre variante a'') un composé bioabsorbable de diisocyanate + b'') un composé bioabsorbable de diamine.
