Moad also notes that the most common grafting modifications made to polyolefins are via maleic anhydride, maleate esters, styrene, maleimides, acrylates and their esters, and vinyl silanes. Other polymer systems (Fink, 2005) that undergo grafting are polystyrene/maleic anhydride (useful for PA6/PS blends), PVC/butylmethacrylate (for improved processi-bility), PET/nadic anhydride, starch/vinyl acetate and starch/methyl acrylate (for improved water resistance).

Primary amine derivatives of the MA-grafted material, such as MA-grafied polyolefins, may be converted to maleimide grafts. This generally improves the impact and heat distortion temperature of plastics, with no sacrifice in transparency, soil release, and other properties.
