Scenario

Processing a polymer often starts with dissolving it — and the wrong solvent means no film, no coating, or an EHS problem. Matching solubility parameters and triaging the processing formulation finds solvents that work and fit the constraints.

Worked example. A coating polymer needs a lower-toxicity solvent that still gives a stable solution and good film formation.

Agent workflow

1. Read the polymer and the processing constraints (EHS, cost, boiling point).
2. Polymer solubility & solvent selection — match solubility parameters and rank candidate solvents / blends.
3. Polymer formulation triage — check the candidate formulation for processing feasibility.
4. Short-list solvents that dissolve the polymer and meet the constraints.

Demo output

A ranked solvent short-list with solubility-parameter match and processing notes, filtered by the EHS/cost constraints. The magic moment: a greener solvent blend matches the polymer as well as the incumbent, clearing an EHS hurdle.

Deterministic vs LLM

• Deterministic — the solubility-parameter matching and formulation triage.
• LLM — the solvent-selection narrative.

Every match is a validated calculation. The agent reads and routes; the engine decides.

Limits

Screening-level solvent guidance, not a substitute for dissolution and film-formation trials. It narrows the solvent set; the lab confirms it.
