标题:Polymer blends and process for preparation
发明人：CHIEN JAMES C W
权利人:AMHERST POLYMER TECHNOLOGY INC
摘要:This invention relates to polymer blends and the process for preparing naturally compatibilized polyolefin blends using a 'one-pot' polymerization of a single monomer, whereby two homopolymers having different structures are produced as well as a third block copolymer having alternating sequences of the two structural segments of the two homopolymers. The formation of the block copolymer is established by solvent extraction and 13C-NMR spectroscopy. The catalyst compositions enabling the direct synthesis of naturally compatibilized polymer blend is prepared by combining four components. The first two components are organometallic complexes of Group IVB or VIIIB elements. The third component is a cocatalyst which irreversibly reacts with at least one ligand on the transition metal complexes. The fourth component is a hydrocarbyl or oxyhydrocarbyl compound of Group IIIA metals, which functions as a cross-over agent.
