The mixing-induced CP violation parameters are also calculated for these decays. We also predict the polarization fractions of $B_s \\to VV$ decays and find that the transverse polarizations are enhanced in some penguin dominated decays such as $\\bar{B_s^0} \\to K ^{*}\\bar{K^{*}}$, $K ^{*}\\rho$.
