- 6. The process defined in claim 4, wherein up to 50% of the structural units having a nitrile group or an N-substituted formamide group, have a nitrile group.
- 7. The process defined in claim 4, wherein the polymer which comprises nitrile-containing repeating units is a homopolymer of acrylonitrile or a copolymer of acrylonitrile with monomers selected from the group consisting of ethylene, propene, 1,3-butadiene and styrene.
- 8. The process defined in claim 7, wherein 16% of the structural units having a nitrile group or an N-substituted formamide group, have a nitrile group.
- 9. The process defined in claim 4, wherein the polymer which comprises N-substituted formamide structural units further comprises, as end groups or side groups, amino groups.
- 10. The process defined in claim 9, wherein from 10 to 100 mol-% of the structural units comprise a nitrile group, an N-substituted formamide group or an amino group.
- 11. The process defined in claim 9, wherein up to 50% of the structural units having a nitrile group, an N-substituted formamide group or an amino group have a nitrile group.
- 12. The process defined in claim 9, wherein 16% or less of the structural units having a nitrile group, an N-substituted formamide group or an amino group have a nitrile group.
- 13. The process defined in claim 9, wherein the polymer which comprises nitrile-containing repeating units is a homopolymer of acrylonitrile or a copolymer of acrylonitrile with monomers selected from the group consisting of ethylene, propene, 1,3-butadiene and styrene.
- 14. The process defined in claim 13, wherein 16% or less of the structural units having a nitrile group, an N-substituted formamide group or an amino group have a nitrile group.
- 15. A polyamine obtained by
- i) catalytically reacting a polymer comprising nitrile-containing repeating units in the presence of hydrogen and carbon monoxide and/or carbon monoxide-releasing compounds to give a polymer comprising N-substituted formamide structural units, and
- ii) hydrolyzing the polymer comprising N-substituted formamide structural units resulting from the catalytic reaction (i) to give the polyamine.
- 16. The polyamine defined in claim 15, wherein wherein the polymer which comprises nitrile-containing repeating units is a homopolymer of acrylonitrile or a copolymer of acrylonitrile with monomers selected from the group consisting of ethylene, propene, 1,3-butadiene and styrene.
- 17. The polyamine defined in claim 16, wherein the polymer which comprises N-substituted formamide structural units further comprises structural units having a nitrile group.
- 18. The polyamine defined in claim 17, wherein the polymer which comprises N-substituted formamide structural units further comprises structural units having an amino group.
- 19. The polyamine defined in claim 18, wherein the polymer which comprises N-substituted formamide structural units comprises from 10 to 100 mol-% of structural units having a nitrile group, an N-substituted formamide group or an amino group.
- 20. The polyamine defined in claim 19, wherein, in the polymer which comprises N-substituted formamide structural units, up to 20% of the structural units having a nitrile group, an N-substituted formamide group or an amino group have a nitrile group.
