Reverse staged impact copolymers

A process for producing ethylene-based in-reactor compositions comprising:

• a) contacting ethylene and optionally a C3 to a C12 alpha-olefin comonomer under polymerization conditions in a first stage in the presence of a first metallocene catalyst system to form Component A;
• b) contacting Component A of step (a) with a C3 to a C12 alpha-olefin monomer under polymerization conditions in a second stage in the presence of a second metallocene catalyst system to form Component B, wherein the first metallocene catalyst system is present in both steps a and b and/or additional metallocene catalyst is added to the reaction mixture between steps a and b and the first metallocene catalyst system may be the same as the second metallocene catalyst system;
• and
• c) obtaining an ethylene-based in-reactor composition comprising Component A and Component B, wherein the ethylene-based in-reactor composition has from greater than 20% to about 85% of ethylene on a mole percentage basis and wherein the polymer composition has a multimodal melting point.
