Abstract
We construct the family of spin chain Hamiltonians, which have affine U(q)g quantum group symmetry. Their eigenvalues coincides with the eig envalues of the usual spin chain Hamiltonians which have non-affine U( q)g(0) quantum group symmetry, but have the degeneracy of levels, corr esponding to affine U(q)g. The space of states of these chains are for med by the tensor product of the fully reducible representations.
