where a' denotes the neighboring segment which bonds with segment a; site A on a
bonds to site B on ot^,. For hard sphere segments that do not overlap,

∆^α*'(r₁,r₂) = Х^“'(Г1,Г₂)У““'(Г1,Г₂),                (4.10)

where K is a constant geometric factor which accounts for the entropie cost associated
with the orientations of the two segments to form the bond. F^aa (rι,r₂) is the
association Mayer-/ function given as

F^αa'(r₁,r₂) = [exp(∕3ε₀ - ∕¾d(^rι, r₂)) - 1],

(4.11)

where ɛo is the bond energy and z∕"₀"_d(r_x, r₂) is the bonding potential. In the limit of
ε₀ → ∞ we have complete association or chain formation. For tangentially bonded
segments the bonding potential, ^ɑ^(rɪ, r₂) is given by

exp[4¾d(rι,r₂)] =

<5(∣rι - r₂∣ - σ^aa')
4π(σ^αc,z)²

(4.12)

and y^aa'(r-L, r₂) is the cavity correlation function for the inhomogeneous hard sphere

reference fluid.
