A parameter,
, 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,
, to that of an otherwise identical linear molecule,
,
with the same
relative molecular mass in the same solvent and at the same temperature, i.e.
.
