From the data generated, it is possible to calculate the degree of branching as a function of MW, and consequently the number of arms of each star polymer
, to securely identify the species present.
Consider a star polymer
with looping branches as shown in Fig.

Determination of zinc content in ZnPc star polymer
was achieved using a double beam flame atomic absorption, Agilent 240FS equipped with cross flow nebulizer after decomposition of the samples by heating in nitric acid till bleaching of the dye.
The SBS [poly(styrene-b-butadiene-b-styrene)] used as the precursor of SBEBS is a star polymer
with four equivalent diblock arms of poly(styrene-6-butadiene) emanating from a silicon-based core with poly(styrene)-b free-ends; it is considered a triblock because the poly(styrene)-b blocks flank a central poly(butadiene)-b block.
developed multi-armed star polymer
complexes for administrating drugs with high doses.

The analysis of reported solution viscosity versus molecular weight data in the literature also suggests that intrinsic viscosities decrease as the functionality of the star polymer
increases (at constant molar mass).
Regarding the use of star polymers
in UV-cured systems, our group has recently studied the cationic photopolymerization of a commercially available cycloaliphatic epoxy resin in the presence of a star polymer
made of a hyperbranched aromatic-aliphatic core and poly(ethylene glycol) arms (15).
