Dendritic macromolecules represent a relatively new aspect of macromolecular chemistry; until around a quarter of a century ago polymer research was focused almost entirely on linear polymers. While most research in the area is still concerned with these traditional polymers, contemporary research also focuses much attention on dendritic molecules. This chapter is intended to supply the reader with the necessary information to understand the subject specific concepts drawn upon in this research, providing relevant examples where appropriate. It is not intended to be an exhaustive account, for this, the reader is directed to a number of comprehensive reviews in the literature. 1.2 - Dendritic Polymers Dendritic polymers are highly branched macromolecules constructed from multi functional monomers, dissimilar from conventionally branched polymers as they are capable of branching from each reactive group on every multi functional monomer. The high degree of branching possessed by these molecules leads to a large number of functionalised end groups; such end groups may be tailored to facilitate solubility in a particular solvent and can dramatically affect their overall properties of the branched system. Accordingly highly branched systems have attracted much interest from research chemists attempting to develop and tailor their behaviour. The term macromolecule was introduced by Hermann Staudinger in ground breaking work for which he received the Nobel Prize in 1953. This landmark paper, published in 1920, proposed that polymeric substances such as rubber and starch were comprised of long chains or short repeating units linked by covalent bonds.
