In this approach, we calculate factorizable and non-factorizable contributions, there are no annihilation contributions due to quark content. We get the branching ratios and polarization fractions for $B_{\small (s)}\to ϕρ$ decays . Our predictions are consistent with the current experimental data.14 pages,one figureHigh Energy Physics - PhenomenologyPerturbative QCD study of $B_{\small (s)}\to ϕρ$ decaystext
