Controlled radical polymerization
Current Opinion in Solid State and Materials Science, 1996Fundamentals of controlled/“living” radical polymerization are given together with a discussion of selected initiating/catalytic systems which provide structural, compositional, and functionality control during radical polymerization. Four systems which enable the synthesis of polymers with low polydispersities (Mw/Mn 10 000), and high degrees of ...

Photoinduced Controlled Radical Polymerization
Macromolecular Rapid Communications, 2010AbstractWell‐controlled radical polymerization of methyl methacrylate can be achieved by in situ photochemical generation of copper (I) complex from air‐stable copper (II) species without using any reducing agent at room temperature. The living character of this polymerization was confirmed by both the linear tendency of molecular weight evolution with

Controlled Radical Polymerization
Journal of Macromolecular Science, Part A, 1994Various methods which lead to the control of molecular weight and polydispersities, and which allow for the preparation of block copolymers by radical polymerization are discussed. Thermal polymerizationof styrenes in the presence of stable radicals, polymerization of vinyl acetate and methyl methacrylate in the presence of chromium complexed by ...

Triazolinyl radicals – new additives for controlled radical polymerization
Macromolecular Chemistry and Physics, 1998The effect of the addition of the triazoline derivative 1 on the radical polymerization of styrene and some methacrylates is discussed. The polymerization of styrene in the presence of 1 exhibits the characteristics of a controlled radical polymerization such as a linear time-conversion development and increasing molecular weights versus conversion ...

Plasmonic-redox controlled atom transfer radical polymerization
Chemical Communications, 2021Plasmonic-ATRP has been developed in which Cu(i) species are (re)generated via photo-redox reactions both directly by hot electrons and indirectly by hot holes.

Macromolecules, 1998
Copper-catalyzed atom transfer radical polymerization (ATRP) is one of the most robust and precise techniques for controlling radical polymerization. The very good control of molecular weights, polydispersities, functionalities, chain composition, and topologies unusual for radical systems combined with the application of transition metals as catalysts

Controlled Radical Polymerization of Styrene by Quinone Transfer Radical Polymerization (QTRP)
Macromolecules, 2004Radical polymerization of styrene falls under control when conducted at 100 °C in the presence of an ortho-quinone, e.g., phenanthrenequinone (PhQ), and a catalytic amount of cobalt(II) acetylacetonate. Criteria for a controlled chain polymerization are fulfilled at least until 50% of monomer conversion, i.e., molar mass increasing with monomer ...

Externally controlled atom transfer radical polymerization
Chemical Society Reviews, 2018ATRP can be externally controlled by electrical current, light, mechanical forces and various chemical reducing agents. The mechanistic aspects and preparation of polymers with complex functional architectures and their applications are critically reviewed.

Controlled Radical Polymerization Initiated by Solvated Electrons
Macromolecular Rapid Communications, 2023AbstractSolvated electron (esol−) is highly reducing species and apt to initiate monomers via one‐electron transfer reaction. Herein, utilizing the esol− solution of Na/hexamethylphosphoramide, radical and anionic initiations are observed respectively, which heavily depend on Na concentrations.
