Abstract

A process for preparing polyolefin blends comprising: a) polymerizing in a solution phase propylene or 1-butene to prepare a polymeric solution containing a semicrystalline polymer component; b) polymerizing in a solution phase 1 -hexene or 1-octene to prepare a polymeric solution containing an amorphous polymer component; c) mixing the polymeric solutions obtained from steps a) and b); d) subjecting the mixture of step c) to a devolatilization step to separate a polyolefin blend comprising a semicrystalline component and an amorphous component; the polymerization steps a) and b) being carried out in two polymerization reactors connected in parallel.
