Low polydispersity poly(N-isopropylacrylamide) with a biotin end-group was obtained in one step from a biotinylated initiator for atom transfer radical polymerization and interacted with streptavidin to generate the thermosensitive polymer-protein conjugate.

Radical-induced addition-fragmentation processes were efficiently used for surface modification of fumed silica, and Z-supported solid CTAs could be reused in presence of excess sacrificial thermal initiator.

A novel supramolecular star polymer is reported, which can be prepared either from atom-transfer radical polymerization (ATRP) of a self-assembled initiator or from self-assembly of a guanosine-capped linear polymer.

Abstract Herein an efficient approach to produce functional polypropylene via solvent assisted solid-phase grafting process is reported, in which acrylic acid, methyl methacrylate and maleic anhydride are used as multi-monomers, 2,2?-azobis(2-methylpropionitrile) initiator ether swelling carrier. The effects of various factors such the species dosage, time temperature, monomer concentrations, r...

Poly(methyl methacrylate) in the brush form is grown from the surface of magnetite nanoparticles by ambient temperature atom transfer radical polymerization (ATATRP) using a phosphonic acid based initiator. The surface initiator was prepared by the reaction of ethylene glycol with 2-bromoisobutyrl bromide, followed by the reaction with phosphorus oxychloride and hydrolysis. This initiator is an...

background the aim of the present study was to investigate the effect of ginger and glibenclamide on oxidative stress markers. oxidative stress is caused by an unbalance between a relative overload of oxidants and depletion of antioxidants, as implicated in the pathogenesis of several chronic diseases, including atherosclerosis and diabetes mellitus. regarding the role of oxidative stress in th...

background & aim: free radicals play a crucial role in the development of tissue damage in various human diseases such as cancer, aging, neurodegenerative disease, malaria and arteriosclerosis, and pathological events in living organisms. antioxidants may have an important role in the prevention of these diseases. the aim of this study is to evaluate potency of scavenging of dpph free radic...

Poly(methyl methacrylate) grafted imogolite clay nanotubes were fabricated via activators regenerated by electron transfer for atom transfer radical polymerization (ARGET ATRP) by designing a water-soluble amphiphilic ATRP initiator that can adsorb onto imogolite surface in an aqueous solution.

Polymer nanocomposites of core–shell structure were prepared by grafting poly(methyl methacrylate) (PMMA) from TiO2 nanoparticle via the surface-initiated polymerization (SIP) strategy. A bifunctional polymerization initiator inspired by L-3,4-dihydroxyphenylalanine (DOPA), a key constituent of mussel adhesive proteins (MAPs), was designed and synthesized for use in SIP from oxide surfaces. The...

The authors conducted free radical polymerization using an initiator to synthesize a copolymer of isobornyl methacrylate—Acrylonitrile (I/A). reactivity ratios I (r1) and A (r2) monomers were determined as r1 = 1.63 ± 0.14, r2 0.61 0.06 for linear KT (Kelen–Tudos) method 1.58, 0.60 the EVM (Error-in-Variable Method). We interpreted 1H 13C{1H} NMR spectra I/A copolymers DEPT-135 2D HSQC spectra....
