ABSTRACT:
This invention relates to polymer alloys and the "one-pot" polymerization process for preparing the same from a single monomer, wherein the product is comprised of two semi-crystalline homopolymers having different micro-structures and a well-defined block copolymer having alternating sequences of the two structural segments of the homopolymers, and with the formed alloy being "naturally" compatible without the need for thermomechanical mixing or addition of a compatibilizing additive, including the presence of a comonomer and formed with catalyst compositions enabling the direct synthesis of "naturally" compatibilized polymer alloy that combines four components: two components being organometallic complexes of Group IVB or VIII elements, a third component being a cocatalyst which irreversibly reacts with at least one nonhapto ligand on the transition metal complex, and a fourth component that is a cross-over agent selected from the group of hydrocarbyl or substituted hydrocarbyl compound of Group IIA, IIB or IIIA elements.
