Access constraints

What governs whether the target is reachable in this feedstock.

  • Crystallinity
  • Reinforcement
  • Additives
  • Grade

Reaction scheme

Controlled amide-bond access.

PA-6 and PA-66 constitutional repeat units sharing the amide linkage. PA-6 evaluation can yield 6-aminohexanoic acid and linear PA-6 oligomers; both materials are assessed for new carboxyl and amine chain ends on retained polymer.

Solid-polyamide conversion remains limited and oligomer-dominated. HMDA and adipate are analytical targets, not demonstrated product yields.
