  • the selection of a surfactant will depend on the product application of interest, and compatibility of the dendritic polymer composition with the surfactant composition.
  • dendritic polymers includes dendrimers, hyperbranched polymers and dendrons .
  • Dendrimers are globular, branched structures, consisting of two or more tree-like dendrons emanating from a single central atom or group called the core. Dendrimers typically consist of several layers of repeating units, called generations, and comprise of branched cells, which must contain at least one branch juncture. Typically at least three different types of branching cells are present in a dendrimer, including (i) a core cell, (ii) interior cells, and (iii) surface or exterior cells.
  • Preferred dendritic polymers are hyperbranched polymers.
  • Hyperbranched polymers are materials consisting of highly branched polymer chains. The concept of highly branched polymers (hyperbranched polymers) was initially introduced by Flory fifty years ago (see, for example, • Flory, P. J. Prinicples of Polymer Chemistry; Cornell
  • Hyperbranched polymers have higher funtional group density than straight-chain ⁇ polymers and conventional branched polymers.
  • Hyperbranched polymers represent a class of dendritic polymers, which contain high levels of non-ideal irregular branching, in which not every repeat unit contains a branch juncture.
  • the degree of branching of a hyperbranched polymer can be controlled by increasing the free chain length between the functional groups. This minimizes the crowding effect, and allows for the production of low as well as higher molecular weight polymers. Due to the large number of branches in such materials, the hydrodynamic volume of a hyperbranched polymer is smaller than that of a linear polymer of the same molar mass. This different relationship between the volume and molecular weight can be directly correlated with the .differences observed in viscosity, solubility, and other physical properties of the hyperbranched polymers.
  • the functionality of the branching cells of dendritic polymers may be controlled such that, for example, the surface branching cells may contain either chemically reactive or inert functional groups.
  • the chemically reactive surface groups can be used for further extension of dendritic growth or for modification of dendritic molecular surfaces.
  • the chemically inert groups may be used to physically modify dendritic surfaces, such as to adjust the ratio of hydrophobic to hydrophilic terminals, and/or to improve the solubility of the dendritic polymer for a particular solvent.
  • Chemical and physical characteristics of. dendritic polymers/ such as reactivity, complex or salt formation, hydrophilicity can be varied and optimized. For instance, dendritic polymers may be derivatized with polar surface groups to make them soluble in polar solvents.
  • a further advantage of globular dendritic polymers, and in particular hyperbranched polymers and dendrimers, is that they possess an internal space.
