We calculate the leading 1/N-f perturbative contributions to the polarized nonsinglet structure functions g(3) and g(5) to all orders in alpha(s). The contributions from the first renormalon pole are determined. It is a measure for the ambiguity of the perturbative calculation and is hypothetically assumed to dominate the power corrections. The corrections Delta(g3) and Delta(g5) are given as functions of the Bjorken variable x and turn out to be negligible. The anomalous dimensions of the leading twist operators are obtained in the next-to-leading order.
