Integrate functionalized resins from LyondellBasell are polyolefins that have been chemically modified to provide anhydride functionality on the polymer backbone. The polar functionality allows Integrate products to function as coupling agents in blends of dissimilar materials, by promoting compatibility in polymer blends, and by providing improved bonding in adhesive formulations. Integrate functionalized resins are used in a variety of applications including coupling agents for filled/reinforced polyolefin formulations and wood (wood fiber) and polyolefin composites (WPC), compatibilizers for polymer blends/alloys, polymer modifiers, dispersion aids and additives for adhesive fibers for woven and nonwoven applications.
