Macromolecular engineering by atom transfer radical polymerization.
This Perspective presents recent advances in macromolecular engineering enabled by ATRP. They include the fundamental mechanistic and synthetic features of ATRP with emphasis on various catalytic/initiation systems that use parts-per-million concentrations of Cu catalysts and can be run in environmentally friendly media, e.g., water. The roles of the major components of ATRP--monomers, initiato...
متن کاملkinetic study of atom transfer radical polymerization of methyl acrylate with polyvinyl acetate macroinitiator
in atom transfer radical polymerization (atrp) of methyl acrylate (ma) with polyvinyl acetate macroinitiator in bulk at 90°c the plots of ln [m]0/[m] increased linearly with reaction time. the apparent propagation rate constant (kp app) of the reaction was obtained from the linear curve and used to calculate the free macroradical concentration ([r°]) in polymerization medium. the [r°] and also ...
متن کاملpoly(styrene-co-butyl acrylate)/clay nanocomposite latexes synthesized via in situ atom transfer radical polymerization in miniemulsion: activators generated by electron transfer approach
w ater born poly(styrene-butyl acrylate)/clay nanocomposite latexes were synthesized by a novel initiating system of activators generated by electron transfer (aget) in a system of atom transfer radical polymerization (atrp). initially, the clay was swelled in a mixture of styrene, butyl acrylate, and hexadecane. the mixture was then sonicated to obtain a stable miniemulsion. to s...

متن کاملMetal-free atom transfer radical polymerization.
Overcoming the challenge of metal contamination in traditional ATRP systems, a metal-free ATRP process, mediated by light and catalyzed by an organic-based photoredox catalyst, is reported. Polymerization of vinyl monomers are efficiently activated and deactivated with light leading to excellent control over the molecular weight, polydispersity, and chain ends of the resulting polymers. Signifi...
