Abstract
A composition results from the blending of a maleic anhydride grafted metallocene linear low-density polyethylene (mLLDPE) or a maleic anhydride grafted metallocene very low-density polyethylene (mVLDPE) with an alkene or olefin polymer composition. The resultant maleic anhydride grafted polymeric composition adheres well to metal films such as aluminum film. The composition also has rheology properties making the composition efficient to use in co-extrusion processes. Also provided is a method for preparing maleic anhydride grafted propylene polymer compositions.
