branching index
in polymers
A parameter, Math - text, characterizing the effect of long-chain branches on the size of a branched macromolecule in solution and defined as the ratio of the mean-square radius of gyration of a branched molecule, Math - text, to that of an otherwise identical linear molecule, Math - text, with the same relative molecular mass in the same solvent and at the same temperature, i.e. Math - ei.
