Grafted polyolefins are polyethylene and polypropylene backbones chemically modified—typically via maleic anhydride, glycidyl methacrylate, acrylic acid, or silanes—to introduce polar functionality while retaining the processability and cost profile of commodity resins . This hybrid polarity makes them the workhorse compatibilizers, tie-layer resins, and adhesion promoters across multilayer packaging, automotive thermoplastic polyolefin systems, glass/mineral-filled and natural-fiber composites, wood-plastic composites, hot-melt adhesives, and polymer recycling/upcycling applications.
