Eqn. 4.47 can be further written as

ln⅛'⁹(r) + £ lnX'(r) = ¾(r) +‰, - v_β≈<(r)), (4.48)

Physically, lnp^^es(r) + ∑2a∈γ<*³) hiʌ^(r) — hιpθ^eg(r), where Po^e,s(^r) ɪɛ the density of

monomers [58],
since bonding at a site on a segment is assumed independent of bonding at the other
sites on the same segment. For the first segment,

ÆW = ∕>ΓW ∏ ⅛.
