The materials-science fragment library for the verifiable polymer-design engine: 18 real addition-polymer monomers (ethylene -> polyethylene, styrene -> polystyrene, vinyl chloride -> PVC, methyl methacrylate-class acrylates, acrylonitrile, vinyl acetate, and more) on a scalable copolymer-segment backbone whose default 4-repeat-unit space enumerates 104,976 states (nUnits and vinylidene knobs push past 1e6+).

Every monomer carries BOTH the drug-likeness FragmentProps and its cited Fedors / Van Krevelen materials-group decomposition, so a combinatorial state carries a real polymer-property vector (solubility parameter, glass transition, density) that rides the GPU enumeration. A side group with no established published group contribution is honestly materials applicable:false, never scored on an invented value.
