Stereospecific cationic RAFT polymerization of bulky vinyl ethers and stereoblock poly(vinyl alcohol) via mechanistic transformation to radical RAFT polymerization of vinyl acetate

open access: yesGiant, 2021
The simultaneous control of molecular weight and tacticity in cationic polymerization remains challenging. Here, we propose a new approach for stereospecific living cationic polymerization by combining cationic reversible addition-fragmentation chain ...

Biocatalytic nanoparticles for the stabilization of degassed single electron transfer-living radical pickering emulsion polymerizations

open access: yesNature Communications, 2020
The use of solid particles to stabilize Pickering emulsions is a particularly attractive avenue, but oxygen sensitivity remains an obstacle in controlled polymerization reactions.

Controlled Radical Polymerization toward Ultra-High Molecular Weight by Rationally Designed Borane Radical Initiators

open access: yesCell Reports Physical Science, 2020
Summary: Ultra-high-molecular-weight (UHMW) polymers can display outstanding properties; however, it is challenging to synthesize UHMW polymers by using external free radical initiators.

Copper(0)-mediated radical polymerisation in a self-generating biphasic system [PDF]

open access: yes, 2013
Herein, we demonstrate the synthesis of well-defined poly(n-alkyl acrylate)s via copper(0)-mediated radical polymerisation in a self-generating biphasic system. During the polymerisation of n-butyl acrylate in DMSO, the polymer phase separates to yield a

Controlled/living radical polymerization

open access: yesMaterials Today, 2005
Until a little more than a decade ago, controlled/living radical polymerization (CRP) would have been an oxymoron. Full control over all aspects of radical polymerization was deemed well-nigh impossible because radical termination reactions occur at diffusion-controlled rates.
