Abstract
Polyolefin blends and processes for forming polyolefin blends are described. The process generally includes forming of polyolefin blends with acrylic monomer system comprising: providing a polyolefin comprising a first portion and a second portion; providing a concentrated monomer system comprising an acrylic monomers and the first portion of the polyolefin, wherein the concentrated monomer system comprises the acrylic monomers at a first concentration and a first portion of the polyolefin; and blending the concentrated monomer system with the a second portion of the polyolefin to form a modified polyolefin, wherein the modified polyolefin comprises a second concentration of acrylic monomers that is less than the first concentration. Described blends can be used as masterbatch concentrates.
