Novel perfluorocyclobutyl (PFCB)-containing polymers formed by click chemistry
关键字：Poly(alkyl aryl) ethers, Perfluorocyclobutane (PFCB), Click chemistry
The synthesis and characterization of a novel class of linear poly(alkyl aryl) ethers containing 1,2,3-triazolyl and perfluorocyclobutyl units have been described. These polymers were readily prepared from the Huisgen’s 1,3-dipolar cycloaddition of poly(ethylene glycol) diazides and 1,2-bis(4-ethynylphenoxy)perfluorocyclobutane that is defined as ‘click chemistry’ recently....

Novel fluorinated polymers bearing phosphonated side chains: synthesis, characterization and properties
关键字：Fluoropolymers，Polyelectrolytes . Phosphonate，Oligo(ethylene oxide)
A new class of aryl trifluorovinyl ether monomers containing phosphonated oligo(ethylene oxide) units were designed and synthesized. Novel fluorinated polymers containing
perfluorocyclobutane and phosphonic acid moieties were prepared from these monomers via the thermal cyclopolymerization and hydrolysis reaction. The structures of these monomers and polymers were characterized ...

Nanogel Star Polymers as Interesting Soft Colloid Materials for Biomedical Applications: No Assembly Required
Polymers have numerous biomedical applications including delivery of therapeutic materials,
imaging applications, tissue regeneration, antimicrobial action and others. We have developed a
route to nanogel core star polymer amphiphiles with control over size, arm number, functionality,
end groups and molecular architecture. Variants of these materials were originally developed to
serve as sacri...

Amphiphilic Hyperbranched Polymers Containing Two Types of β-Cyclodextrin Segments: Synthesis and Properties
关键字：amphiphilic,core-multishell structure,β-cyclodextrin,hyperbranched, synthesis
Amphiphilic hyperbranched polymers carrying two types of b-cyclodextrin groups including
ionic and covalent bonding were synthesized via atom transfer radical polymerization
and immobilization reaction. Their inclusion capabilities for single or double-guest
molecules were investigated by UV-visible spectroscopy.
Using Chlorambucil and Lonidamine as the double model
drugs, their encapsulation...
