Title (EN) COMPOSITION COMPRISING ACID ANHYDRIDE-GRAFTED POLYOLEFIN
(FR) COMPOSITION COMPRENANT UNE POLYOLEFINE GREFFEE A L'ANHYDRIDE D'ACIDE
Abstract:
(EN) 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.
(FR) L'invention concerne une composition résultant du mélange d'un polyéthylène basse densité linéaire métallocène greffé à l'anhydride maléique (mLLDPE) ou d'un polyéthylène très basse densité métallocène greffé à l'anhydride maléique (mVLDPE) avec une composition polymère d'alcène ou d'oléfine. La composition polymère greffée à l'anhydride maléique ainsi obtenue présente une bonne adhérence sur des films métalliques tels que des films d'aluminium. Cette composition possède également des propriétés rhéologiques lui permettant d'être utilisée de façon efficace dans des processus de co-extrusion. L'invention concerne également un procédé de préparation de compositions polymères de propylène greffé à l'anhydride maléique.
