Regular star macromolecule

Fig.1. Regular star macromolecules with/=3,4, and 8 arms of identical length. The arms or rays can consist of rather stiff chains, but are in most cases flexible chains. The global structure is determined by the overall shape of the whole macromolecule the internal structure is indicated by a domain that is much smaller than the overall dimension but still larger than a few Kuhn segments...

Note 2 If the arms of a star macromolecule are identical with respect to constitution and degree of polymerization, the macromolecule is termed a regular star macromolecule. 

Polymer composed of regular macromolecules, regular star macromolecules, or regular comb macromolecules. 

Since the successful synthesis of dendritic macromolecules from low MW monomers [14a], research has also been performed in the area of dendritic polymers [14b, 15]. Dendritic polymers are obtained by attaching or growing several end-standing arms onto a central regular star polymer. This procedure is repeated in a generational manner, see Figure 3.3. 

Fig. 24. Contraction factors for star-branched macromolecules as a function of the number of arms. The full line represents strictly regular stars, the dashed line one that for stars with polydisperse arms (MyM =2), the dotted line according to Daoud and Cotton [29]. The symbols represent the data from the literature. The deviation at large / represents the stretching of the arms due to overcrowding...
