Investigation of Thiol-ene Addition Reaction on Poly(isoprene) Under UV Irradiation: Synthesis of Graft Copolymers with "V"-Shaped Side Chains
Poly(isoprene) (PI) with pendant functional groups was successfully synthesized by thiol-ene addition reaction under 365 nm UV irradiation, and the functionalized PI was further modified and used to prepare graft copolymers with ‘‘V’’- shaped side chains. First, the pendant ASCH2CH(OH)CH2OH groups were introduced to PI by thiol-ene addition reaction between 1-thioglycerol a...

Endosomal pH-Activatable Poly(ethylene oxide)-graft-Doxorubicin Prodrugs: Synthesis, Drug Release, and Biodistribution in Tumor-Bearing Mice
Novel poly(ethylene oxide)-graft-doxorubicin (PEO-g-DOX) prodrugs with DOX covalently conjugated to PEO via a pH-sensitive hydrazone bond were developed. PEO-g-DOX conjugates could be readily prepared in the following steps: (i) anionic ring-opening copolymerization of ethylene oxide (EO) and allyl glycidyl ether (AGE) afforded functional PEO with controlled molecular weights, low polydispersities...

Self-Assembly and Dual-Stimuli Sensitivities of Hydroxypropylcellulose-graft-poly(N,N-dimethyl aminoethyl methacrylate) Copolymers in Aqueous Solution
The self-assembly and pH- and thermo-sensitivities properties of hydroxypropyl cellulose-graft-poly(N,N-dimethyl aminoethyl methacrylate) (HPC-g-PDMAEMA) copolymers in aqueous solutions were investigated by transmittance, dynamic light scattering (DLS), and 1H NMR spectroscopy. Micelles with different structure can be formed by varying either pH value or temperature. At low pH, e.g., 3.0, the HPC ...

Smart Assembly Behaviors of Hydroxypropylcellulose-graft-poly(4-vinyl pyridine) Copolymers in Aqueous Solution by Thermo and pH Stimuli
Thermo- and pH-sensitive graft copolymers, hydroxypropylcellulose-graft-poly(4-vinyl pyridine) (HPC-g-P4VP), were synthesized via atom transfer radical polymerization (ATRP) and characterized. The thermo- and pH-induced micellization and stimuli-responsive properties of HPC-g-P4VP graft copolymers in aqueous solution were investigated by transmittance, 1H NMR, dynamic light scattering (DLS), and s...

Functionalization of carbon nanotubes by corona-discharge induced graft polymerization for the reinforcement of epoxy nanocomposites
A novel methodology for grafting polymer onto the surface of multiwalled carbon nanotubes (MWCNTs) was explored in this study. MWCNTs was first treated by corona discharge at room temperature and then transferred to a vinyl monomer glycidyl methacrylate (GMA) under the protection of nitrogen to initiate the graft polymerization of GMA. Compared with conventional plasma processes under low pressure...

Fe3O4@poly(2-hydroxyethyl methacrylate)-graft-poly(3-caprolactone) magnetic nanoparticles with branched brush polymeric shell
Well-defined monodisperse Fe3O4@poly (2-hydroxyethyl methacrylate)-graft- poly(e-caprolactone) (Fe3O4@PHEMA-g-PCL) magnetic nanoparticles with novel topological structure, i.e., with branched brush polymeric shell, were successfully prepared by the combination of atom transfer radical polymerization (ATRP) and ring-opening polymerization (ROP). Oleic acid stabilized monodisperse Fe3O4

Surface-initiated graft polymerization on multiwalled carbon nanotubes pretreated by corona-discharge at atmospheric pressure
Surface-initiated graft polymerization on multi-walled carbon nanotubes pretreated with a corona discharge at atmospheric pressure was explored. The mechanism of the corona-discharge-induced graft polymerization is discussed. The results indicate that MWCNTs were encapsulated by poly(glycidyl methacrylate) (PGMA), demonstrating the formation of PGMA-grafted MWCNTs (PGMA-g-MWCNTs), with a grafting ...

Covalently attached graft polymer monolayer on organic polymeric substrate via confined surface inhibition reaction
A grafting technique was proposed for the preparation of polymer monolayer on polymeric substrate. On the basis of our recent work on polymer-supported inhibitor (PSI), hydroquinone (HQ) was first implanted onto polypropylene (PP) surface through UV-initiated grafting. The resulting immobilized HQ was used as PSI for the thermal-induced free radical polymerization (FRP) of acrylic acid (AA). ...
