  Kinetic theory of dissipative particle dynamics is developed in terms of a
Boltzmann pair collision theory. The kinetic transport coefficients are
computed from explicit collision integrals and compared favourably with
detailed simulations. Previous theory is found to correspond to a weak
scattering limit, or Vlasov theory, and previously reported discrepancies with
simulations are thereby resolved. In the large dissipation limit, we find
qualitatively new scaling properties for the transport coefficients.
