We investigated theoretically the properties of spin polarization in organic polymer contacting magnetic atoms. Dependence of the spin polarization on the strength of the electron-phonon coupling in a polymer and the spin-dependent effect of the interface coupling were discussed. By modulating the strength of spin splitting, we found that the spin polarization within an organic chain is weaker than that within a metal chain, but stronger than that within a semiconductor.
