“…[52,53] proposed an efficient system based on alkoxyamine 4 as an example (Figure 4). The numerical calculations on the kinetics of ESCP performed by Nikitin et al [48] revealed the influence of different factors, in particular, the rate of initiation, spin capturing, including spin capturing rate constant and nitrone concentration, on the kinetics of the process and the characteristics of the polymer. Interestingly, the fast initiation of polymerization in ESCP can lead to the decrease in "living" chains that is absolutely contrary to NMP, where the rapid decomposition of the initiator is required for reaching the controlled regime.…”

“…The state of the art of this socalled in situ NMP as of 2008 was reviewed [137] by Detrembleur and coworkers. An interesting variant of in situ NMP which uses alkoxyamines formed by addition of polymeric radicals to nitrones or nitroso compounds is the socalled en hanced spin capturing polymerization [138] (ESCP).…”

This article describes some selected results of my 30 years as an industrial researcher. During this time, I had the chance to work on many very different projects. About two thirds of them were dealing with the fascinating interaction of radicals and polymers. Of the more than 350 million tons of industrial polymers produced worldwide every year, about 50% are made by the radical polymerization of monomers that are often stabilized against undesired premature polymerization by addition of polymerization inhibitors. Stabilizers are necessary to protect the majority of polymeric materials during their service life from radical degradation processes triggered by oxygen, heat or light. Modification of the polymeric architecture can be easily achieved via radical polymer analogous reactions. One of the most important developments in polymer science in the last 25 years is controlled radical polymerization. Recently, radical bearing redox-active polymers emerged as promising in energy storage applications, for example, in organic radical batteries. Our contributions to the fields mentioned above are described with examples of: a) novel benzofuranone stabilizers for polymers; b) the serendipidous discovery of novel dyestuffs; c) eco-friendly polymerization inhibitors; d) novel nitroxides and alkoxyamines for the first industrial realization of controlled radical polymerization; e) novel and safe radical initiators; f) nitroxide radicals bearing polymers for electrochemical applications.

“…In the simplest situation, a univariate description is selected which corresponds in practice to the consideration of the chain length as the only variate in the microkinetic model. [117][118][119][120][121][122][123][124][125][126][127][128][129][130][131][132][133][134] In many cases, this univariate approach is even limited to the calculation of the average chain lengths of the CLD (e.g. x n and x m ).…”

The performance of polymeric materials depends strongly on the control over the polymer microstructure during the synthesis step. In this review, attention is paid to the potential of microkinetic modelling to facilitate the identification of optimal reactants and reaction conditions to design the polymer microstructure in bulk and solution (post) polymerisation processes. Focus is on living polymerization, reversible deactivation radical polymerization (RDRP) and "click" chemistry techniques, covering both batch and continuous synthesis approaches. A description according to the increasing level of macromolecular detail and thus modelling complexity is provided, including not only the characterization of the polymer microstructure via a finite number of variates (e.g. chain length, overall composition and branching content) but also its explicit visualisation by the simulation of the architecture and monomer sequences of a representative number of individual polymer chains. Several complementary case studies are included to demonstrate the high relevance of model-based design for the development of improved and novel synthetic protocols for precision control
