TL;DR: In this article, a multi-block copolymer is defined for use in forming a multinode copolym, containing two or more segments or blocks differing in chemical or physical properties, and a polymerization process using the same, and the resulting polymers, wherein the composition comprises the admixture or reaction product resulting from combining: (a) a first metal complex olefin polymerization catalyst, (b) a second metal complex OLEF polymerisation catalyst capable of preparing polymers differing from the polymer prepared by catalyst under equivalent polymerization conditions, and (
