In this article, the fundamental principles 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 polymerisation.Abstract:
Fundamentals 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 functionality are: nitroxide-mediated polymerization of styrene and styrene copolymers; organometallic compounds used for polymerization of acrylates; atom transfer radical polymerization of various monomers; and the degenerative transfer process. Also important in this field are new structural features and potential applications of controlled radical polymerization.read more

Controlled/living radical polymerization: Features, developments, and perspectives
TL;DR: In this article, a review of recent mechanistic developments in the field of controlled/living radical polymerization (CRP) is presented, with particular emphasis on structure-reactivity correlations and "rules" for catalyst selection in ATRP, for chain transfer agent selection in reversible addition-fragmentation chain transfer (RAFT) polymerization, and for the selection of an appropriate mediating agent in stable free radical polymerisation (SFRP), including organic and transition metal persistent radicals.

Functional polymers by atom transfer radical polymerization
TL;DR: Atom transfer radical polymerization (ATRP) is one of the most successful methods to polymerize styrenes, (meth)acrylates and a variety of other monomers in a controlled fashion, yielding polymers with molecular weights predetermined by the ratio of the concentrations of consumed monomer to introduced initiator and with low polydispersities as discussed by the authors.

Kinetics of Living Radical Polymerization
Atsushi Goto,Takeshi Fukuda +1 more
TL;DR: In this article, a review of fundamental kinetic features of living radical polymerization (LRP) is presented, where the authors show that the product from LRP can have a low polydispersity, provided that the number of terminated chains is small compared to the number potentially active.

Narrow molecular weight resins by a free-radical polymerization process
TL;DR: In this paper, free radical polymerization was used to obtain polystyrene and poly(styrene-co-butadiene) with narrow polydispersity (1.19-1.36) in the presence of 2,2,6, 6,6-tetramethyl-1-piperidinyloxy using benzoyl peroxide as initiator

Controlled Living Radical Polymerization - Halogen Atom-Transfer Radical Polymerization Promoted by a Cu(I)Cu(II) Redox Process
TL;DR: An extension of ATRA to atom transfer radical addition, ATRP, provided a new and efficient way to conduct controlled/living radical polymerization as mentioned in this paper, using a simple alkyl halide, R-X (X = Cl and Br), as an initiator and a transition metal species complexed by suitable ligand(s), M t n /L x, e.g., CuX/2,2'-bipyridine, as a catalyst.
