    Notes: Abstract. This work continues our considerations in [15], where we discussed existence and regularity results for the mean curvature flow with homogenious Neumann boundary data. We study the long time evolution of compact, smooth, immersed manifolds with boundary which move under the mean curvature flow in Euclidian space. On the boundary, a Neumann condition is prescribed in a purely geometric manner by requiring a vertical contact angle between the unit normal fields of the immersions and a given, smooth hypersurface $\vec\Sigma$ . We deduce estimates for the curvature of the immersions and, in a special case, we obtain a precise description of the possible singularities.

    Notes: Abstract. In this work we study the behaviour of compact, smooth, immersed manifolds with boundary which move under the mean curvature flow in Euclidian space. We thereby prescribe the Neumann boundary condition in a purely geometric manner by requiring a vertical contact angle between the unit normal fields of the immersions and a given, smooth hypersurface ${\vec\Sigma}$ . We deduce a very sharp local gradient bound depending only on the urvature of the immersions and ${\vec\Sigma}$ . Combining this with a short time existence result, we obtain the existence of a unique solution to any given smooth initial and boundary data. This solution either exists for any $t〉0$ or on a maximal finite time interval $[0,T]$ such that the curvature explodes as $t \rightarrow T$ .
