Let M and N be some standard operator algebras on complex Banach spaces X and Y , respectively, and F(x) be a polynomial with no repeated roots and deg(F) ≥ 2, such that F(0) = 0. We characterize the forms of surjective linear maps φ : M −→ N which preserve the nonzero products of operators that annihilated by F(x).
