It is shown that K-equilibration fission can explain the decrease of mass resolved fission fragment anisotropy at larger mass asymmetries. Two competing mechanisms contribute to the anisotropy. The effective moment of inertia and K{sub 0}{sup 2} decreases with the increase of mass asymmetry and contribute to the increase of anisotropy. On the other hand, for larger asymmetries, the barriers are higher and lifetimes are longer. Such systems are more K equilibrated and will have smaller anisotropy. {copyright} {ital 1997} {ital The American Physical Society}
