    • Highly branched polyamides prepared in a single step procedure of condensation polymerization of multifunctional monomer reactants comprising amine and carboxylic acid functional groups. Polymerization proceeds by reaction of an amine group of a first monomer unit with an acid group of a second monomer unit to form a reaction product having an amide linkage between the first and second monomer units and repetition of such amidation reaction between additional amine groups and acid groups of the multi-functional monomers and reaction products of the multi-functional monomers. In the present invention, in order to obtain a water soluble or dispersible hyperbranched polyamide, at least one of the multifunctional monomer unit reactants contains an amine, phosphine, arsenine or sulfide group, such that the highly branched polyamide contains in the backbone thereof an N, P, As or S atom capable of forming an onium ion.

    • 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 &Dgr;[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 process for polymerization of vinyl monomers is described comprising (a) forming an onium salt complex comprising a transition metal component by reacting an onium salt with a transition metal species, and (b) polymerizing vinyl monomers in the presence of the formed transition metal containing onium salt and an organic halide initiator compound. The present invention provides a novel method for living polymerization of vinyl monomers, which provides a high level of macromolecular control over polymerization process and which leads to more uniform and more controllable polymeric products. In accordance with preferred embodiments of the invention, the organic halide initiator comprises an organic chloride or bromide compound, as the onium salt complexes which comprise a transition metal provide increased catalystic effect required for use of such initiator compounds relative to organic iodide initiator compounds.
