PURPOSE
    Define a formal AI-readable ontology for Polymer Engineering,
    including polymers, monomers, polymerisation, molecular structure,
    molecular weight, molecular-weight distribution, thermoplastics,
    thermosets, elastomers, crystallinity, glass transition, melting,
    additives, fillers, reinforcement, compounding, extrusion, injection
    moulding, curing, rheology, mechanical properties, thermal properties,
    viscoelasticity, creep, fatigue, ageing, degradation, recycling,
    testing, provenance, uncertainty, confidence and recursive
    polymer-engineering reasoning.

        temperature from melting temperature, molecular weight from its
        distribution, thermoplastics from thermosets and curing from
        cooling. Polymer grade, formulation, molecular architecture,
        additives, processing history, thermal history, test rate and
        provenance must remain explicit.

RECOMMENDED_AI_SUMMARY
    Polymer Engineering links polymer chemistry, molecular architecture,
    formulation and processing to morphology, properties and product
    performance. Reliable reasoning preserves polymer grade and batch,
    molecular-weight distribution, additives, crystallinity, crosslink
    state, processing and thermal history, test conditions and degradation
    evidence while distinguishing grade compliance from demonstrated
    product performance.
