Abstract
The invention concerns a mixture comprising by weight, the total being 100%, 1 to 100% if a polyamide block copolymer consisting of a basic polyolefin chain and on an average at least a polyamide graft wherein: the grafts are fixed to the basic chain by the radicals of an unsaturated monomer (X) having a function capable of reacting with a polyamide with amine terminal, the radicals of the unsaturated monomer (X) are fixed to the basic chain by grafting or copolymerization from its double bond; 99 to 0% of a flexible polyolefin with elastic modulus in flexure less than 50 MPa at 23° C. and having a crystalline melting point ranging between 60° C. and 100° C. Said mixtures are useful for making films, tanks, geomembrane protective fabrics produced by extrusion, products obtained by calendering, thermocladding/forming, protective films for electric cables and skins using slush molding technique.
