- 8. The polymer defined in claim 7, wherein from 10 to 100 mol-% of the polymer units comprise a nitrile group, an N-substituted formamide group or an amino group.
- 9. The polymer defined in claim 7, comprising up to 50 mol-% of nitrile groups based on the sum of the molar amounts of nitrile groups, N-substituted formamide groups and amino groups.
- 10. The polymer defined in claim 7, comprising up to 20 mol-% of nitrile groups based on the sum of the molar amounts of nitrile groups, N-substituted formamide groups and amino groups.
- 11. The polymer defined in claim 7, comprising from 16 mol-% or less of nitrile groups based on the sum of the molar amounts of nitrile groups, N-substituted formamide groups and amino groups.
- 12. The polymer defined in claim 2, wherein from 10 to 100 mol-% of the polymer units comprise a nitrile group or an N-substituted formamide group.
- 13. The polymer defined in claim 2, comprising up to 50 mol-% of nitrile groups based on the sum of the molar amounts of nitrile groups and N-substituted formamide groups.
- 14. The polymer defined in claim 2, comprising up to 20 mol-% of nitrile groups based on the sum of the molar amounts of nitrile groups and N-substituted formamide groups.
