  The spin effects in nucleon-nucleon scattering are calculated in the
framework of the dynamic model taking into account interactions at large
distances and the strong form factors; the model factorization of the $NN$
amplitude into the spin-dependent hadron-pomeron vertex and high-energy
spinless pomeron is obtained. Theoretical predictions for polarization and
$A_{nn}$ are made for the diffraction range at the RHIC energies.
