Polycaprolactam composition having improved melt spinnability and method for improving melt spinnability of polycaprolactam |
| 摘要 |
When magnesium oxide in which the half-width of the X-ray diffraction profile at (200) as determined according to a specific method is at least 0.3 is incorporated in an amount of 0.05 to 2.0% by weight in polycaprolactam, a polycaprolactam composition having an improved spinnability is obtained.
