Abstract
We show that the meson-cloud model predicts a
substantial polarization of the sea quarks of the nucleon, because of the
interference of 
and 
exchanges. This polarization is
strongly flavour-dependent. The model gives an explanation of the
strong increase in the structure function g1 that has isospin
I=1 at small x.
