| 摘要 |
This invention relates to a polymer composition comprising monomeric units derived from caprolactam, wherein a) the caprolactam content is at most 0.3 wt % based on the total amount of polymer composition, and b) wherein [acid end groups]-[amine end groups]>=meq/kg, whereby [acid end groups] is the concentration of acid end groups in the polymer composition in meq/kg and [amine end groups] is the concentration of amine end groups in the polymer composition in meq/kg; c) and wherein the RSV is at least 2.8. This invention also relates to a process for producing this polymer composition as well as articles made thereof. |
