Title:
POLYAMIDE-GRAFTED POLYMERS, PHOTOVOLTAIC MODULES WITH A BACKSHEET FILM COMPRISING A POLYAMIDE-GRAFTED POLYMER AND MANUFACTURING PROCESS AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2010/069546
Kind Code:
A3
Abstract:
One subject of the invention is the use of α film as a protective backsheet in a photovoltaic module, said film comprising at least one layer of a composition containing a polyamide-grafted polymer, this polyamide-grafted polymer comprising a polyolefin backbone containing a residue of at least one unsaturated monomer (X) and at least one polyamide graft, in which: • the polyamide graft is attached to the polyolefin backbone by the residue of the unsaturated monomer (X) that comprises a functional group capable of reacting via a condensation reaction with a polyamide having at least one amine end group and/or at least one carboxylic acid end group; • the residue of the unsaturated monomer (X) is attached to the backbone by grafting or copolymerization; said polyamide-grafted polymer comprising, relative to its total weight: • from 40 to 95% by weight of the polyolefin backbone comprising the unsaturated monomer (X); and • from 5 to 60% by weight of polyamide grafts, and the melting point or glass transition temperature of the polyamide grafts being greater than or equal to 85°C. The invention also relates to a process of manufacturing a photovoltaic module, to a photovoltaic module and also to the use of this module for producing electricity.
