We discuss our studies of polarized parton distributions which are related to the RHIC-Spin project. First, the parametrization of unpolarized parton distributions is explained as an introduction to general audience. Second, activities of the RHIC-Spin-J working group are reported. In particular, preliminary results are shown on the parametrization of polarized parton distributions. Third, we discuss numerical solution of the DGLAP Q2 evolution equations for longitudinally polarized and transversity distributions. An efficient and accurate computer program is important for analyzing future RHIC experimental data.
