  We study root separation of reducible monic integer polynomials of odd
degree. Let h(P) be the naive height, sep(P) the minimal distance between two
distinct roots of an integer polynomial P(x) and sep(P)=h(P)^{-e(P)}. Let
e_r*(d)=limsup_{deg(P)=d, h(P)-> +infty} e(P), where the limsup is taken over
the reducible monic integer polynomials P(x) of degree d. We prove that e_r*(d)
<= d-2. We also obtain a lower bound for e_r*(d) for d odd, which improves
previously known lower bounds for e_r*(d) when d = 5, 7, 9.
