    • A new polymerization process (atom transfer radical polymerization, or ATRP) based on a redox reaction between a transition metal (e.g., Cu(I)/Cu(II), provides “living” or controlled radical polymerization of styrene, (meth)acrylates, and other radically polymerizable monomers. Using various simple organic halides as model halogen atom transfer precursors (initiators) and transition metal complexes as a model halogen atom transfer promoters (catalysts), a “living” radical polymerization affords (co)polymers having the predetermined number average molecular weight by Δ[M]/[I]0 (up to Mn>105) and a surprisingly narrow molecular weight distribution (Mw/Mn), as low as 1.15. The participation of free radical intermediates in ATRP is supported by end-group analysis and stereochemistry of the polymerization. In addition, polymers with various topologies (e.g., block, random, star, end-functional and in-chain functional copolymers [for example, of styrene and methyl (meth)acrylate]) have been synthesized using the present process. The polymeric products encompassed by the present invention can be widely used as plastics, elastomers, adhesives, emulsifiers, thermoplastic elastomers, etc.

    • A polymerization process for producing highly branched polyesters is disclosed comprising reacting functional groups A and B of multi-functional branching monomer reactants of the formula A—L—Bn, where one of A and B represents an epoxide group, the other of A and B represents an acid chloride group, L represents a linking group between A and B, and n is at least 2. In accordance with a specific embodiment of the invention, branched polyesters are obtained which have a number average molecular weight of at least 1000 and a ratio of weight average molecular weight to number average molecular weight of less than 2. The invention provides a process for producing highly branched polyesters in one reaction step. The invention has the capability of making highly branched structures of high molecular weight and low polydispersity and has the advantages of not requiring multi-step reactions and purification. The invention yields highly branched polyesters having a multiplicity of very reactive epoxy or acid chloride or both on the outside surface which can be further converted to other functional groups, including polymerizable groups and initiating groups, which can undergo further chain extensions.
