Materials Properties - cited group-contribution polymer properties (no AI)

Compute the standard POLYMER / MATERIALS design properties over a repeat unit from PUBLISHED additive group-contribution methods, cited on every value and with NO fit and NO tuning: amorphous molar volume and cohesive energy (Fedors 1974), cohesive energy density and the Hildebrand solubility parameter delta = sqrt(Ecoh/Vm), glass-transition temperature Tg = (sum Yg)/M (Van Krevelen), and amorphous density rho = M/Vm.

What it is

Compute the standard POLYMER / MATERIALS design properties over a repeat unit from PUBLISHED additive group-contribution methods, cited on every value and with NO fit and NO tuning: amorphous molar volume and cohesive energy (Fedors 1974), cohesive energy density and the Hildebrand solubility parameter delta = sqrt(Ecoh/Vm), glass-transition temperature Tg = (sum Yg)/M (Van Krevelen), and amorphous density rho = M/Vm. Vm, Ecoh and Yg are additive descriptor channels that ride the same GPU enumeration as the drug-likeness descriptors; delta, Tg and rho are finalized once from the accumulated sums. A group with no established published contribution returns applicable:false, never a guess. Anchor-validated against experimental polyethylene / polypropylene / PVC / polystyrene / PMMA.

Honest scope

Deterministic and citation-backed: every figure is exact arithmetic or a cited rule. Any year- or jurisdiction-indexed value is a confirmable input, never an eternal hardcode. This is a computation tool, not professional (legal, tax, medical, or financial) advice - confirm against the controlling authority for your context.
