Solution feed of multiple catalysts

A method to polymerize olefins in a gas-phase reactor comprising introducing a first catalyst, a second catalyst, and at least one activator into the reactor in a liquid carrier, wherein the first catalyst is structurally different from the second catalyst, wherein each catalyst is activated independently without having to compete for the at least one activator, wherein the first catalyst, the second catalyst and the activator(s) are combined in the liquid carrier before being introduced into the reactor and wherein at least one catalyst is a bulky ligand type metallocene catalyst.
