Preferred Label : branching index;
Detailed label : branching index in polymers;
IUPAC definition : A parameter, g, 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, sb2 , to that of an otherwise identical linear
molecule, sl2 , with the same relative molecular mass in the same solvent and at
the same temperature, i.e. g sb2 / sl2 .;
