Abstract
The present invention consists of the use, in a chlorinated and filled thermoplastic composition containing at least one chlorinated thermoplastic resin and at least one mineral filler, as an agent improving the thermal stability and UV resistance of the said composition, of a linear amphiphilic copolymer characterized in that: It also concerns a manufacturing process for a chlorinated and filled thermoplastic composition implementing the said copolymer, as well as the composition obtained directly by the said process.
