Origins and Development of Initiation of Free Radical Polymerization Processes

International Journal of Polymer Science, 2009
At present worldwide about 45% of the manufactured plastic materials and 40% of synthetic rubber are obtained by free radical polymerization processes. The first free radically synthesized polymers were produced between 1910 and 1930 by initiation with ...

Transformation Journey of Monomers into Copolymers by Free Radical Polymerization (FRP), Atom Transfer Radical Polymerization (ATRP), and Ionic Polymerization (IP)

Within the scope of this chapter, we provide a quick introduction to a variety of polymerization techniques that transform monomers into copolymers. We also emphasize the distinctive mechanisms that these strategies employ in order to exert control over the structure of polymers.

Applying Dynamic Monte Carlo Simulation for Living Free Radical Polymerization Processes: Emphasis on Atom Transfer Radical Polymerization (ATRP) [PDF]

, 2011
Modeling is the applications of methods to analyze complex, real-world problems in order to make predictions about what might happen with various actions. When it is too difficult, time consuming, costly or dangerous experiments, the modeler resort to computer simulations, or having a computer program imitate reality, in order to study situations and ...

An Innovative Approach for Tailoring Molecularly Imprinted Polymers for Biosensors—Application to Cancer Antigen 15-3

Biosensors
This work presents a novel approach for tailoring molecularly imprinted polymers (MIPs) with a preliminary stage of atom transfer radical polymerization (ATRP), for a more precise definition of the imprinted cavity. A well-defined copolymer of acrylamide

Achieving Less Than 100 ppb Total Metal Ion Concentration in ESCAP Resins Synthesized by Atom Transfer Radical Polymerization

Macromolecular Materials and Engineering
In the photolithography process of integrated circuits （IC） manufacturing, it is desired that the photoresist resins have both smaller polydispersity index (PDI) and lower trace metal ion concentrations.

Compartmentalization in Atom Transfer Radical Polymerization (ATRP) in Dispersed Systems

Macromolecular Theory and Simulations, 2006
AbstractSummary: Compartmentalization in atom transfer radical polymerization (ATRP) in dispersed systems at low conversion (<10%) has been investigated by means of a modified Smith–Ewart equation focusing on the system n‐butyl acrylate/CuBr/4,4′‐dinonyl‐2,2′‐dipyridyl at 110 °C.

Recent Developments in Atom Transfer Radical Polymerization (ATRP): Methods to Reduce Metal Catalyst Concentrations

ChemPhysChem, 2012
AbstractAtom transfer radical polymerization (ATRP) was initially developed in the mid‐1990s, and with continued refinement and use has led to significant discoveries in new materials. However, metal contamination of the polymer product is an issue that has proven detrimental to widespread industrial application of ATRP.
