Polymer data

Polymer databases live in a peculiar universe where identities are primarily indexed based on reactant. Not structure nor composition nor reaction per se, but primary reactant.
This is how polymer chemists talk and think, i.e., information about polypropylene is naturally indexed by propylene.
From an information management POV, this is not ideal and it causes much confusion, e.g., copolymers are often indexed by multiple reactants, but not all.
It is tempting to reorganize polymer data into a rigorous form. This could be done by reindexing the data based on reaction rather than a particular reactant.
However, the "primary reactant" organization of polymer data is so prevalent in the polymer literature that it is probably unreasonable to attempt a reorganization. Cross-indexing is likely to be most successful by classification methods, the result of which could be integratable into the chemical universe.
