Abstract
An agent is provided which renders compatible at least two incompatible thermoplastic polymers. The agent contains one di- or trisequenced copolymer comprising at least one N-vinyl-pyrrolidone or methyl (meth) acrylate telomer and one mono- or difunctional oligomer selected from the group consisting of an ethylenically unsaturated polymerizable monomer, or a polycondensable monomer, or a lactam. The agent is prepared by condensation of the telomer with the oligomer and is used in the preparation of alloys of incompatible thermoplastic polymers.
