The flow properties of dilute solutions of linear, star, hyperbranched and dendrimeric polymers have been the subject of numerous studies. However, no systematic analysis has been carried out for the case of single-chain nanoparticles (SCNPs) of different nature, which are unimolecular soft nano-objects consisting of individual polymer chains collapsed to a certain degree by means of intramolec...

Two different polymer systems have been studied in regards to their potential for functionalization to introduce new characteristics to the polymer. The first polymer system is a poly(arylene ether) with a truly pendant sulfone group from the monomer 3,5-difluorodiphenylsulfone. The work entails incorporating a bromine moiety onto the monomer for the versatile ability to bring in functional gro...

With oleic acid grafting modification, a series of hyperbranched-linear polymer surfactants (HLPS) were prepared by hydroxyl-terminated hyperbranched polymer (HBP), which was gained through a step synthesis method using trimethylolpropane and AB2 monomer. The AB2 monomers were obtained through the Michael addition reaction of methyl acrylate and diethanol amine. The structures of HLPS were char...

This work demonstrates the synthesis, characterization and application of a hyperbranched polyethyleneimine/polysulfone (HPEI/PSf) thin fi lm composite (TFC) membrane. The membrane was accessed via an interfacial polymerization of trimesoyl chloride and HPEI. The membrane samples were characterized by Fourier Transform Infrared-Attenuated Total Refl ectance (FTIR-ATR) s...

Introduction Highly branched polymers play an increasingly important role in interface and surface sciences, since their distinctive chemical and physical properties can be used advantageously as functional surfaces and as interfacial materials. Hyperbranched polymers grafted onto surfaces have also become a field of growing interest. Depending upon the substrates, it can be divided into 3D, 2D...

An acidic tea polysaccharide (ALTPS), isolated from green tea ( Camellia sinensis ), was characterized as a hyperbranched glycoprotein containing the acidic heteropolysaccharide chains and the protein residues from the results of UV-vis, FTIR, one- and two-dimensional NMR, GC, GC-MS, and amino acid analyses. Solution properties of ALTPS were investigated by static and dynamic light scattering a...
