ABSTRACT:
The invention relates to melt-miscible polyolefin blends, and a process for preparing the melt-miscible blends, of two or more polyolefins. Matching, within defined limits, the segment length of a modifying polyolefin with the segment length of a primary polyolefin, such as polypropylene or an ethylene/alpha-olefin copolymer, provides blends of the "matched" components which blends were heretofore unknown to be melt-miscible. A broad range of polyolefin blend compositions, and of polyolefin blends containing other polymers made compatible or dispersible with the polyolefin blend compositions, are defined, all of the blend compositions having at least one melt-miscible polyolefin phase.
