Local orientational mobility in regular hyperbranched polymers.
We study the dynamics of local bond orientation in regular hyperbranched polymers modeled by Vicsek fractals. The local dynamics is investigated through the temporal autocorrelation functions of single bonds and the corresponding relaxation forms of the complex dielectric susceptibility. We show that the dynamic behavior of single segments depends on their remoteness from the periphery rather t...
متن کاملlow stress acrylated hyperbranched polymers
The objective of this study was to investigate the behavior of highly functional acrylates, during isothermal ultraviolet (UV) curing. The materials included a penta-functional acrylate and two acrylated hyperbranched polymers, one with a stiff polyester core and one with a more flexible polyether core. In particular, the influence of UV intensity and reactive blend composition on structural tr...
متن کاملMembrane Functionalization with Hyperbranched Polymers
Polymer membranes have been modified with hyperbranched polymers with the aim to generate a high density of hydrophilic functional groups at the membrane surface. For this purpose hyperbranched polymers containing amino, alcohol, and carboxylic acid end groups were used for membrane modification, respectively. Thus, surface potential and charges were changed significantly to result in attractiv...
متن کاملHyperbranched Polymers in Absorption: Experimental Co2 Solubilities
Oxidative coupling of methane (OCM) is an approach for the direct catalytic conversion of methane to higher hydrocarbons, which is currently being investigated at the Berlin Institute of Technology within the cluster of excellence UniCat (Unifying Concepts of Catalysis). Hereby, the conversion to ethylene is the major goal of the process. In the downstreaming process subsequent to the OCM react...
متن کاملHyperbranched polymers for controlled release of cisplatin.
Hyperbranched polymers based on a polyether and polyester have been modified and used as macromolecular ligands for the anticancer drug cisplatin, giving controlled release of the drug over 7 days.
