Abstract
A polyamide-grafted polyolefin composition in which the grafting rate of the composition is between 41% and 70% by weight. Also, a thermoplastic composition including a polyolefin backbone comprising a residue of at least one unsaturated monomer (X) and a plurality of polyamide grafts, in which: the polyamide grafts are attached to the polyolefin backbone by the residue of the unsaturated monomer (X) comprising a functional group capable of reacting by a condensation reaction with a polyamide having at least one amine end and/or at least one carboxylic acid end, the residue of the unsaturated monomer (X) is attached to the backbone by grafting or copolymerization, wherein the polyamide grafts represent from 41% to 70%, preferably from 45% to 70%, by mass of said polyamide-grafted polymer. Also, a thermoplastic film for encapsulating and/or protecting the back ('backsheet') of a photovoltaic module that includes said polyamide-grafted polyolefin composition.
