We present a measurement of the branching fraction and the longitudinal polarization fraction of B super(0) arrow right rho super(+)rho super(-) decays, as well as the time-dependent CP violating parameters in decays into longitudinally polarized rho super(+)rho super(-) pairs with Belle's final data set of 772x10 super(6)BB pairs, at the Gamma(4S) resonance, collected at the asymmetric-energy e super(+)e super(-) collider KEKB. We obtain Bernoulli(B super(0) arrow right rho super(+)rho super(-))=(28.3+ or -1.5(stat)+ or -1.5(syst))x10 super(-6), functionof sub(L)= 0.988+ or -0.012(stat)+ or -0.023(syst) , scriptA sub(CP)=0.00+ or -0.10(stat)+ or -0.06(syst), scriptS sub(CP)=?0.13+ or -0.15(stat)+ or -0.05(syst). We perform an isospin analysis to constrain the Cabibbo-Kobayashi-Maskawa angle varphi sub(2) and obtain two solutions with varphi sub(2)=(93.7+ or -10.6)degrees , being most compatible with other Standard-Model based fits to the data.
