We present a Monte Carlo (MC) study of W± and Z0 production of longitudinally polarized proton collisions at a center of mass (CMS) energy of 500 \rm GeV. All results were obtained with the SPHINX MC code. We consider two different types of polarized parton distributions with large and small gluon polarization. Various spin asymmetries are found to be sensitive to the shape of the polarized gluon distribution between 0.1\stackrel<∼x\stackrel<∼0.5. The asymmetries are approximately constant with respect to the transverse momentum carried by the W± and Z0, \em except if the first moment of the gluon polarization is large. In this case some W± asymmetries show a significant variation with transverse momentum.
