An ultra-low oligomer content bio-based nylon 5x resin and method of making the same
By employing a multi-stage heating, gradient vacuum, and inert gas micro-flow process, the problem of high oligomer content in bio-based nylon 5X resin was solved, resulting in high-performance, low-moisture-content, and narrow-molecular-weight-distribution bio-based nylon 5X resin suitable for high-end fibers and engineering plastics.

AI Technical Summary
The existing bio-based nylon 5X resin has an excessively high oligomer content, which leads to a decline in mechanical properties and insufficient long-term stability, making it difficult to meet the stringent requirements of high-end fibers and engineering plastics.
By employing a multi-stage heating, gradient vacuum, and inert gas micro-flow process, and by gradually controlling the temperature and vacuum level, combined with physical removal using inert gas micro-flow, the oligomer content is significantly reduced, thus preparing bio-based nylon 5X resin with ultra-low oligomer content.
It significantly reduces oligomer content, improves the mechanical properties and durability of materials, meets the performance requirements of high-end fibers and engineering plastics, and is also green and sustainable.
