Abstract
Abstract A general overview of polyamide technology is presented, with emphasis on commercial practice and technology developed since 1980. The article includes coverage of nomenclature; history; economic, health, and environmental aspects; and physical properties, including crystallinity, solubility, and piezoelectric effects. There is an extensive discussion of chemical properties including methods of preparation (direct amidation, reaction of acid chlorides, and ring‐opening polymerization of lactams via hydrolytic, anionic, and cationic processes); chemical reactions (acidolysis, aminolysis, alcoholysis, ammonolysis, transamidation, transesteramidation, and grafting); and degradation reactions (hydrolysis, thermal degradation, thermooxidation, photodegradation and photooxidation, biodegradation, and mechanodegradation). The manufacturing practices for most commercial nylons that are presented include monomer production for nylon‐6,6, nylon‐6, nylon‐4,6, nylon‐6,9, nylon‐6,10, nylon‐6,12, nylon‐11, nylon‐12, nylon‐12,12, and nylon‐13,13. Nylon‐6,6 and nylon‐6 are compared in detail. There are also discussions of copolyamides, mixed aliphatic–aromatic, and wholly aromatic polyamides. Extensive tables are presented which list CAS Registry Numbers, physical properties, and world‐wide manufacturers of most polyamides.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
