Abstract
The present invention relates to an isotactic polypropylene obtained by metallocene catalysis, onto which is grafted a functional monomer.The invention also relates to a composition which may form part of the composition of a coextrusion binder. This composition according to the invention comprises isotactic polypropylene obtained by metallocene catalysis, grafted and then optionally diluted with at least one polyolefin (C1) and/or in at least one polymer of elastomeric nature (D).The invention also relates to a multilayer structure comprising a layer (L) comprising the above binder, and, directly attached thereto, a layer (E):
