Controlled synthesis of graft polymer through the coupling reaction between the appending β-keto ester and the terminal amine
A new method to synthesize graft polymer with controlled graft density (?) through the coupling reaction between the appending β-keto ester and the terminal amine is proposed. Following this method, the backbone polymer of poly[2-(acetoacetoxy) ethyl methacrylate] (PAEMA) containing the appending β-keto ester is synthesized by reversible addition-fragmentation chain transfer polymerizati...

Backbone-collapsed intra- and inter-molecular self-assembly of cellulose-based dense graft copolymer
The self-assembly of cellulose-based amphiphilic dense grafting copolymer ethyl cellulose graft poly(acrylic acid) (EC-g-PAA) in a selective solvent was measured by dynamic light scattering (DLS) and transmission electron microscopy (TEM). Our aim is to realize the intra- or inter-molecular association by collapsing the backbone of dense grafting copolymers. The effects of grafting density, gr...

Surface modification of polyethylene by plasma pretreatment and UV-induced graft polymerization for improvement of antithrombogenicity
The purpose of this study was to enhance blood compatibility of polyethylene (PE) films. Glycidyl methacrylate (GMA) was grafted onto the surface of PE by Ar plasma pretreatment and UV-induced graft polymerization without photo-initiator, then heparin was immobilized onto the poly (glycidyl methacrylate) segments. The surface compositions and microstructure of GMA graft polymerized PE films were s...

Water-Soluble Starlike Poly(acrylic acid) Graft Polymer: Preparation and Application as Templates for Silver Nanoclusters
Water-soluble starlike polymers containing concentrated carboxyl groups were conveniently synthesized via the combination of “click” chemistry and atom transfer radical polymerization (ATRP). The starlike polymer was composed of a shorter polyacrylate main chain and longer poly(acrylic acid) side chains. Alkyne and azide groups were introduced to the structure units of the main chain b...

Synthesis of pH- and temperature-responsive chitosan-graft-poly(2-(N,N-dimethylamino)ethyl methacrylate) copolymer and gold nanoparticles stabilization by its micelles
Novel pH- and temperature-responsive chitosan-graft-poly[2-(N,N-dimethylamino)ethyl methacrylate] (chitosan-g-PDMAEMA) copolymers were successfully synthesized by homogeneous atom transfer radical polymerization (ATRP) under mild conditions. Chitosan macroinitiator was prepared by phthaloylation of amino groups of chitosan and subsequent acylation of hydroxyl groups of chitosan with 2-bromoisobuty...

Synthesis of Cellulose- graft -Poly(N, N-Dimethylamino-2-Ethyl Methacrylate) Copolymers via Homogeneous ATRP and Their Aggregates in Aqueous Media.
Cellulose-graft-poly(N,N-dimethylamino-2-ethyl methacrylate) (cellulose-g-PDMAEMA) copolymers were prepared by homogeneous atom transfer radical polymerization (ATRP) under mild conditions. Cellulose macroinitiator was successfully synthesized by direct acylation of cellulose with 2-bromopropionyl bromide in a room temperature ionic liquid (RTIL), 1-allyl-3-methylimidazolium chloride. Copolymers w...

Synthesis, self-assembly and drug release behaviors of pH-responsive copolymers ethyl cellulose-graft-PDEAEMA through ATRP
The pH-responsive ethyl cellulose graft poly(2-(diethylamino) ethyl methacrylate) (EC-g-PDEAEMA) copolymers were synthesized through atom transfer radical polymerization (ATRP). Kinetic analysis confirmed the reaction is living and controllable. The graft copolymers can form micelles in acid aqueous medium. The critical micelle concentration (CMC) of the graft copolymers decreases with the in...

Synthesis and characterization of star graft copolymers with asymmetric mixed V-shaped side chains via click chemistry on a hyperbranched polyglycerol core.
The star graft copolymers composed of hyperbranched polyglycerol (HPG) as core and well defined asymmetric mixed ‘‘V-shaped’’ identical polystyrene (PS) and poly(tert-butyl acrylate) as side chains were synthesized via the ‘‘click’’ chemistry. The V-shaped side chain bearing a ‘‘clickable’’ alkyne group at the conjunction poin...
