We prove that the Wigner transforms of a large class of "macroscopic" solutions converge in r-th mean to solutions of a linear Boltzmann equation, for any finite value of r in R_+. This extends previous results where convergence in expectation was established.AMS-Latex, 36 pages, 3 figures. Title reworded. Final version, to appear in Commun. Math.
