Preferred Label : steric factor;
Detailed label : steric factor in polymers;
IUPAC definition : The ratio, σ, of the root-mean-square end-to-end distance of a polymer chain with
unperturbed dimensions, r2 0(1/2), to that of a freely rotating chain with the
same structure, r2 0,f(1/2), i.e. sqrt( r2 0/ r2 0,f), in the limit of infinite
chain length. The steric factor reflects the effect of hindrance to free rotation.;
