A process for the preparation of a hyperbranched polymer comprising initiating polymerization of and thereafter copolymerizing a solution comprising an AB monomer and a C monomer, each of which is individually polymerizable, to produce growing chains in which A and B are reactive groups that react independently of each other in which A contains a group polymerizable in living fashion, C is a monomer that contains a group polymerizable in living fashion, B is a precursor of an activated B* species capable of effecting the living polymerization of A and C as a result of being activated, wherein B is activated and B* adds to any A or C polymerizable group and wherein each of A, B and C are compatible with each other.
A hyperbranched polymer produced from the copolymerization reaction of an AB monomer and a C monomer in which A and B are reactive groups that react independently of each other and in which the group A is a polymerizable group, the C monomer contains a group that can be polymerized by A* or B*, the group B is a precursor of an activated moiety B* capable of effecting the polymerization of A and C as a result of being activated, wherein activated B adds to any A or C polymerizable group, and said hyperbranched polymer has living character in that said polymer has active sites A*, B* and C* that can add to any A or C polymerizable groups.
