These copolymers formed dendron (hyperbranched) and linear micelles, respectively, which were compared in terms of their stabilities in serum, micelle-serum protein interactions, and in vivo biodistributions.
HPPV exhibits good solubility and processability, a high glass transition temperature (Tg) and high fluorescence quantum yield in chloroform solution (much higher than fully conjugated hyperbranched and linear PPV).
Comparison of the physical properties between the dendritic, hyperbranched and linear structures showed that thermal properties, such as glass transition temperature and thermogravimetric analysis, were independent of macromolecular architecture.
The hyperbranched and the linear PAAs generally formed polyplexes with plasmid DNA with sizes around 200 nm and positive zeta potentials ranging from + 10 to + 22 mV at polymer/DNA weight ratios equal or higher than 3/1.
The molecular dynamics of two polyurethanes with different architecture (linear and hyperbranched) and their blends with compositions 80/20 and 65/35 have been studied by dielectric spectroscopy and dynamic mechanical analysis yielding results complementary to those obtained by differential scanning calorimetry.
This review comprehensively describes the chemical polymerization methods to synthesize polysaccharides with different compositions and architectures (linear, branched, and hyperbranched) and the synthetic procedures to polysaccharide mimetics possessing, for example, amine linkages, amide linkages, and carbonate linkages.
The different strategies for synthesis of degradable and conducting polymers containing conducting oligomers are summarized and discussed here as well as the influence of different macromolecular architectures such as linear, star-shaped, hyperbranched and cross-linked DECPs.
Star-branched polymers consisting of poly(ε-caprolactone) (PCL) attached to third generation dendrimer, hyperbranched and dendron cores have been studied together with linear PCL analogues.
Advances in macromolecular synthesis, self-assembling polymers, hyperbranched and interpenetrating polymer networks and various types of nanocomposites, provide opportunities for developing novel binder systems.
Dendrimers are globular polymeric macromolecular three-dimensional structures, which are hyperbranched and well organized as shown in Fig. 2.
