Claim:
1. A method for manufacturing a loaded plastic material having improved thermal stability, comprising: preparing by radical copolymerization, a copolymer consisting of units obtained from: a) a (meth)acrylic monomer, and b) a macromonomer having the formula (I): wherein: m and n are non-zero whole numbers less than 150, A and B refer to alkyl groups having 2 to 4 carbon atoms, wherein alkyl groups A are different from alkyl groups B, and the alkyl groups A and B are distributed in a block or statistical fashion, R designates a polymerizable unsaturated function, and R′ represents hydrogen or an alkyl group having 1 to 40 carbon atoms; wherein the radical copolymerization is a member selected from the group consisting of radical polymerization in a solution, radical polymerization in a direct or reverse emulsion, radical polymerization in a suspension or precipitation in solvents, radical polymerization in the presence of catalytic systems and transfer agents, and controlled radical polymerization; and incorporating the copolymer formed into the loaded plastic material, wherein the plastic material comprises at least one plastic resin selected from the group consisting of thermoplastic resins and heat-setting resins, wherein when the plastic material comprises a thermoplastic resin, the thermoplastic resin is at least one member selected from the group consisting of halogenated resins, styrenic resins, acrylic resins, polyolefins, polycarbonate resins, unsaturated polyester resins, polyurethane resins, polyamide resins, and mixture of these resins, and wherein when the plastic material comprises a heat-setting resin, the heat-setting resin is at least one member selected from the group consisting of acrylic resins, phenoplasts, aminoplasts, and ethoxinlines.
