Abstract
Hyperbranched polymers are synthesized with uniform structure based on one pot polymerization technique in confined space with nanometer scale, e.g. micelles in a microemulsion system. The segregated space in micelles or polymerizing nanoparticles is expected to regulate the growth of hyperbranched polymers by confining polymer-polymer reaction inside each individual locus. The obtained hyperbranched polymers have uniform size, similar to the size of nanoparticles, as indicated by a narrow molecular weight distribution of the polymers.
