    摘要: Provided are functionalized polypropylene adhesive compositions having a desirable range of melt flow rate. These compositions are obtained by grafting at least one impact polypropylene copolymer or by co-grafting a blend containing at least one impact polypropylene copolymer and at least one random polypropylene copolymer. The polypropylene copolymer(s) are grafted with one or more ethylenically unsaturated carboxylic acids or derivatives of these acids, such as anhydrides. Maleic anhydride is a preferred grafting monomer. Also provided is a multilayer film or sheet structure containing at least one barrier layer and at least one adhesive layer produced from the functionalized polypropylene adhesive composition. The multilayer film or sheet structure may also contain at least one predominantly polypropylene-based layer. In addition, a multilayer film or sheet structure is provided in which a barrier layer or a primer layer is adjacent to at least one layer that is produced from a dry blend or a melt blend of the functionalized polypropylene adhesive composition with a polypropylene matrix polymer.
