Abstract
The Alexander modules of a link are the homology groups of the universal abelian cover of the complement of the link. For a link of $n$-spheres in ${S^{n + 2}}$, we show that, if $n \geqslant 2$, the Alexander modules ${A_2}, \ldots ,{A_n}$ and the torsion submodule of ${A_1}$ are all of type $L$. This leads to a characterization, below the middle dimension, of the polynomial invariants of the link. These results were previously proven for the special case of boundary links.
