Multibrominated Hyperbranched Polymers: Synthesis and Further Functionalizations by ARGET ATRP or Click Chemistry

Macromolecular Rapid Communications, 2012
AbstractHyperbranched polymers with multiple alkyl bromide peripheral groups were synthesized by the copolymerization of styrene with ethylene glycol dimethacrylate (2.5, 5.0, 7.5, or 10.0 mol% relative to styrene) in the presence of CBr4 (10–20‐fold excess vs. the radical initiator).

Polycationic Nanoparticles for siRNA Delivery: Comparing ARGET ATRP and UV-Initiated Formulations

ACS Nano, 2014
In this work, we develop and evaluate polycationic nanoparticles for the delivery of small interfering RNA (siRNA). Delivery remains a major challenge for translating siRNA to the clinic, and overcoming the delivery challenge requires effective siRNA delivery vehicles that meet the demands of the specific delivery strategy.

Functional brush-decorated poly(globalide) films by ARGET-ATRP for bioconjugation.

Macromolecular bioscience, 2015
Formation of hydroxyl functionalized poly(macrolactone) films was achieved by a combination of enzymatic ring opening polymerization of globalide and thiol-ene coupling reactions. Reaction with α-bromoisobutyryl bromide yielded ATRP initiator functional films.

Confined polymerization: ARGET ATRP of MMA in the nanopores of modified SBA-15

Polymer, 2017
Abstract Rod-like mesoporous SBA-15 silica particles were surface modified by different silane coupling agents firstly, then polymethyl methacrylate (PMMA) was prepared in the confined nanopores of the SBA-15 via activators regenerated by electron transfer for atom transfer radical polymerization (ARGET ATRP). The PMMA/SBA-15 nanocomposites and PMMAs

Ethyl Lactate, a New Green Solvent for ARGET ATRP of Methyl Acrylate

Chemistry Letters, 2017
The use of ethyl lactate solvent in the activators regenerated by electron transfer atom transfer radical polymerization (ARGET ATRP) of methyl acrylate is demonstrated. The solvent has good solubility for both polymers and monomers and is cheap and relatively nontoxic.

Structure and Properties of Silk Grafted with 2-Hydroxyethyl Methacrylate by ARGET ATRP

Advanced Materials Research, 2012
In this work, silk was reacted with 2-bromoisobutyryl bromide to obtain silk macroinitiator for activators regenerated by electron transfer for atom transfer radical polymerization (ARGET ATRP). Silk macroinitiator was grafted with 2-hydroxyethyl methacrylate (HEMA) via ARGET ATRP method to produce grafted silk in water aqueous.
