Which amine monomers have been tried in step 2 across the project?21 Aug 02:37
Amines recorded in step 2 (the acrylate-intermediate step) across the 9076 records:
1. Epomine SP-018 — by far the most common; appears in step 2 of ~40 records (batches 1, 5, 10–17, 20–22, 24–26, 27A–C, 28, 29B/D, 30, 32–37A, 39, 41, 48, 49, 50, 54A, 55, and stubs NO-49, notebook p19). Recorded names vary ("Epomine SP- 018", "SP-18 (Epomine)", "Epoimine SP-018").
2. Lupasol G-20 / G-20 WF — used as the amine in step 2 of batches 2, 3, 4, 6, 7, 8, 18, 19, 27D, 27E, 38C, 38D (with 2-ethylhexyl acrylate, except 27E); also appears in step 2 of batch 22 alongside SP-018.
3. "Eptamine - 8p-18 (SP-18)" — the step-2 amine of the Baten No-57 stub, read by OCR/handwriting from notebook pages 21-22. The record itself labels it "(SP-18)", i.e. likely the same SP-18 amine under a garbled reading — treat as an unresolved conflict rather than a distinct amine.
Gaps:

Gaps:
- Batch 40's step-2 list contains only "2 ethyl hexyl acrylate; AIBN" — no amine is recorded.
- Several step-2 entries are unnamed ("Step-1 product", e.g. batch 29A), so their amine is not individually stated.
- Batches 55 and 55D have step-2 material lists present but empty in the record.
