Patent ID: 8912294

Claim:
Polyamine A1 of formula (I) or (II) wherein a stands for an integer from 2 to 100; A stands for an a-valent radical of a polyamine B1 after removal of a primary amino groups, wherein the a-valent radical has at least 3 amino groups that are secondary or primary amino groups and a number of the secondary amino groups is greater than a number of the primary amino groups; either R 1 and R 3 each independently stands for an alkyl, cycloalkyl, aryl, or arylalkyl group with 1 to 12 C atoms, the alkyl, cycloalkyl, aryl, or arylalkyl group with 1 to 12 C atoms optionally having ether groups or halogen atoms, and R 2 stands for a hydrogen atom or for an alkyl, cycloalkyl, aryl, or arylalkyl group with 1 to 12 C atoms; or R 2 and R 1 together stands for a divalent hydrocarbon radical that is part of a carbocyclic ring with 5 to 8 C atoms, or R 2 and R 1 together stands for a divalent hydrocarbon radical that is part of a substituted carbocyclic ring with 5 to 8 C atoms, and R 3 stands for an alkyl, cycloalkyl, aryl, or arylalkyl group with 1 to 12 C atoms, the alkyl, cycloalkyl, aryl, or arylalkyl group with 1 to 12 C atoms optionally having ether groups or halogen atoms; or R 2 and R 3 together stands for a divalent hydrocarbon radical that is part of a carbocyclic ring with 5 to 8 C atoms, or R 2 and R 3 together stands for a divalent hydrocarbon radical that is part of a substituted carbocyclic ring with 5 to 8 C atoms, and R 1 stands for an alkyl, cycloalkyl, aryl, or arylalkyl group with 1 to 12 C atoms, the alkyl, cycloalkyl, aryl, or arylalkyl group with 1 to 12 C optionally having ether groups or halogen atoms; and R 4 and R 5 each independently stands for an alkyl, cycloalkyl, aryl, or arylalkyl group with 1 to 12 C atoms, the alkyl, cycloalkyl, aryl, or arylalkyl group with 1 to 12 C optionally having ether groups or halogen atoms.
