In this talk results from a new QCD analysis in Leading (LO) and Next-to-Leading (NLO) Order are presented. New parametrizations of the polarized quark and gluon densities are derived together with parametrizations of their fully correlated 1\sigma error bands. Furthermore the value of \alpha _s(M_Z²) is determined. Finally a number of low moments of the polarized parton densities are compared with results from lattice simulations. All details of the analysis are given in J. Blümlein, H. Böttcher, Nucl. Phys. B636, 225 (2002).
