Patent ID: 7754782

Claim:
A process for the closure or binding of cellular tissues, comprising applying at least one adhesive system comprising A) prepolymers comprising isocyanate groups obtained from A1) aliphatic isocyanates; and A2) polyols with number-averaged molecular weights of ≧400 g/mol and average OH group contents of from 2 to 6; and B) amino group-containing aspartate esters of general formula (I) wherein X is an n-valent organic radical obtained by removal of the primary amino groups of an n-functional amine; R 1 and R 2 are, identically or differently, organic radicals comprising no Zerevitinov active hydrogen; and n is a whole number of at least 2; and/or C) reaction products of prepolymers comprising isocyanate groups with aspartate esters according to B) to the cellular tissue to be closed or bound.
