| abstract |
The invention relates to a method for the preparation of copolymers in the form of a star comprising at least two types of polymer arms having a different chemical nature. The method comprises a radical polymerization phase for a composition comprising at least one cross-linking monomer, a free radical source, and at least two first generation (co)polymers having a different chemical nature and optionally a different molecular mass. The invention also relates to star copolymers which can be prepared by said method, and the uses thereof. |
