Abstract
We present a general method for the solution of the renormalization group equations for the non-forward parton distributions on the two-loop level in the flavour singlet channel based on an orthogonal polynomial reconstruction. Using this formalism we study the effects of the evolution on recently proposed model distribution functions.

19 pages, LaTeX, 3 figures; factor of momentum fraction in front of forward gluon density, lost in numerical modeling of input gluon SPD from double distribution, is recovered: evolution curves in Figs. 2 and 3 are rescaled accordingly
