We compute the gluonic contributions to the spin-dependent weak structure functions [Formula: see text](i=1, 3, 4), using the factorization theorem in the minimal subtraction scheme, [Formula: see text]. We have considered the most general case where the quark flavor masses are distinguished and the gluons are off mass shell. The gluonic contribution to the first moment of [Formula: see text] is found to vanish and [Formula: see text] do not receive leading order gluonic contribution. These results are shown to be free of mass singularities.
