Use of amphiphilic copolymers as agents that improve thermal stability and resistance to ultraviolet rays of chlorinated and charged thermoplastic materials, and manufacturing process of said materials
The use, in a chlorinated and charged thermoplastic composition containing at least one chlorinated thermoplastic resin and at least one mineral filler, as an agent that improves the thermal stability and ultraviolet resistance of the composition, of a linear amphiphilic copolymer, characterized in that: - it is made up of at least one hydrophilic monomer and at least one hydrophobic monomer, - it has a weight average molar mass between 5,000 g / mol and 20,000 g / mol and a polymolecularity index of less than or equal to 3 , and preferably a weight average molar mass between 10,000 g / mol and 15,000 g / mol and a polymolecularity index of less than or equal to 2.5
