  Abstract:
Polarized parton distribution functions(PPDF) has been calculated in the improved valon model using next-to-leading order approximation. The Bernstein polynomial method has been applied to do direct fits. Our predictions for next-to-leading order of polarized parton distributions and proton structure function have been compared with leading order.
