The convective Cahn–Hilliard (CCH) equation, ut + (uxx + u − u 3 )xx − (D/2)(u 2 )x = 0, has been suggested recently for the description of several physical phenomena, including spinodal decomposition of (driven) phase separating systems in an external field, instability of steps moving on a crystal surface, and faceting of growing, thermodynamically unstable surfaces. In this paper the dynamics of domain walls (kinks) governed by the convective Cahn–Hilliard equation is studied by means of asymptotic and numerical methods. A special attention is paid to the dynamics of kink pairs and triplets that play crucial role in the coarsening (Ostwald ripening) process. For the driving parameter D
