  In the last years a lot of work has been concentrated on the study of the
behaviour at infinity of polynomial maps. This behaviour can be very
complicated, therefore the main idea was to find special classes of polynomial
maps which have, in some sense, nice properties at infinity. In this paper, we
completely determine the complex algebraic monodromy at infinity for a special
class of polynomial maps (which is complicated enough to show the nature of the
general problem).
