The invention relates to a modified polylactam containing recurring units of lactam and minor amounts of a lactam derivative having one or more non-polymerisable functional groups directly or indirectly attached to the carbon atoms of the lactam ring and wherein the functional group comprises a heteroatom. The invention further relates to a process for the preparation of the polylactam, to the use of the modified polylactam, to fibres made from the modified lactam and to the lactam derivative and its production. |
