  A dynamical version of the Widom-Rowlinsom model in the continuum is
considered. The dynamics is modelled by a spatial two-component birth-and-death
Glauber process where particles, in addition, are allowed to change their type
with density dependent rates. An evolution of states is constructed as the
unique weak solution to the associated Fokker-Planck equation. Such solution is
obtained by means of its correlation functions which belong to a certain Ruelle
space. Existence of a unique invariant measure and ergodicity with exponential
rate is established. The mesoscopic limit is considered, it is related with the
verification of the chaos preservation property.
