Kinetics of the excitation of a non-equilibrium polariton condensate, called bogolon, is studied by using the quantum Boltzmann equation coupled with the Gross-Pitaevskii equation for polariton and the rate equation for the non-resonant exciton-reservoir which is derived from the non-equilibrium Green functions. The time-, space- and momentum-resolved population of the bogolon and condensate polariton are calculated numerically after the switch-on of a cw non-resonant pump in the exciton-reservoir regime. The bogolon distribution approaching to a thermal equilibrium distribution is studied in detail.
