description A polymer composition may include a plurality of ethylene-based polymers forming a multimodal composition distribution, each having a distinct crystallization peak in a CEF curve. A process of making a polymer composition may include melt blending a plurality of polyethylenes with different microstructural characteristics in the molten state. Another process of making a polymer composition may include polymerizing ethylene and an optional alpha olefin in combination with a plurality of metallocene catalysts in a polymerization reactor to form a plurality of ethylene based polymers. Yet another process of making a polymer composition may include polymerizing ethylene and an optional alpha olefin in combination with a multimetal catalyst in a polymerization process to form a plurality of ethylene based polymers.
