Patent ID: 6894144

Claim:
Elastomer material based on N-alkylaziridino compounds with a base component which contains an aziridino compound and with a catalyst component which contains at least one acid-acting compound, both components being mixed before use, wherein, as the acid-acting compound of the catalyst component, one or more boric acid complexes are used which can be obtained by reaction of boric acid and/or a boric acid derivative with at least one OH-functional compound, the OH functions being able to be present wholly or partly protected, and this reaction being carried out either as an upstream reaction between boric acid and/or a boric acid derivative and at least one such OH-functional compound or during or after the preparation of the catalyst component or by mixing the catalyst component with the base component which then contains at least one such OH-functional compound and the at least one OH-functional compound containing at least one and up to 10 OH groups wherein the OH-functional compound is selected from the group consisting of i) compounds which contain at least one 1,2-dihydroxy and/or at least 1,3-dihydroxy group; ii) compounds which have at least one phenolic OH group; and iii) α-hydroxy-carboxylic acids, wherein the OH-functional compound containing at least one and up to 10 OH groups has the general structural formula wherein R1, R2 and R3 represent the same or different radicals selected from the group consisting of hydrogen, aliphatic, cycloaliphatic, aromatic and araliphatic substituents with 1 to 30 C atoms in each, of which one or more C atoms can be replaced by R1′ and R2′ being the same or different wherein R1′ and R2′ are aliphatic, cycloaliphatic, aromatic or araliphatic bivalent radicals with 1 to 30 C atoms.
