RAFT Step-Growth Polymerization of Diacrylates

ACS Macro Letters, 2022
RAFT step-growth polymerization was previously demonstrated with monomers that bear low rate of homopropagation to favor the chain transfer process; by contrast, acrylates are known to be fast homopropagating monomers, thereby posing serious challenges for RAFT step-growth.

RAFT Polymerization with Triphenylstannylcarbodithioates (Sn-RAFT)

ACS Macro Letters, 2015
A new range of tin-based reversible addition-fragmentation chain-transfer (RAFT) agents is described and evaluated for the polymerization of acrylamides, methyl acrylate and styrene. These organometallic compounds are highly reactive reversible transfer agents which allow an efficient control of the polymerization of substituted acrylamide monomers ...

Micellar RAFT/MADIX Polymerization

ACS Macro Letters, 2017
We apply the RAFT/MADIX technique to the micellar copolymerization of acrylamide and 2-acrylamido-2-methylpropanesulfonic acid sodium salt with a hydrophobic monomer, 4-tert-butylstyrene. The resulting polymers have well-controlled molecular weight distributions.

Coenzyme-Catalyzed Electro-RAFT Polymerization

ACS Macro Letters, 2017
Here we report an electrochemically switchable reversible addition-fragmentation chain transfer polymerization (eRAFT). A new family of biochemical coenzymes are discovered that can be used as highly efficient electroredox catalysts to mediate this polymerization.

Accelerated Continuous Flow RAFT Polymerization

Macromolecules, 2010
Homogeneous continuous flow RAFT polymerizations with N-isopropylacrylamide (NIPAM) as monomer and a trithiocarbonate as chain transfer agent are investigated. Polymerization rates are considerably increased compared to reactions in batch due to more uniform heating of the solution.

Utilization of Poor RAFT Control in Heterogeneous RAFT Polymerization

Macromolecules, 2021
Heterogeneous reversible addition–fragmentation chain transfer (RAFT) polymerization exhibits considerable promise in polymer and colloid synthesis. During the research of RAFT polymerization, good RAFT control is always an important goal to achieve while poor RAFT control is considered to be a lack of success.

Microwave‐Assisted RAFT Polymerization

Israel Journal of Chemistry, 2012
AbstractAdvances in controlled radical polymerization (CRP) have facilitated access to well‐defined polymers with controlled molecular weight, topology, and functionality. However, despite the benefits afforded by many CRP techniques, control over these key polymer attributes often comes at the expense of polymerization rate.

RAFT Polymerization in Bulk and Emulsion

Macromolecular Symposia, 2007
AbstractDetailed models of the RAFT polymerization in both non‐segregated (bulk) and segregated (seeded emulsion) systems are presented. It is shown that satisfactory agreements between experiments and models can be achieved, and that effects such as inhibition and retardation, or the polymerization behavior at high conversions can be readily explained.

Anticoagulant Heparin Mimetics via RAFT Polymerization

Biomacromolecules, 2019
Heparin, a sulfated polysaccharide derived from animal sources, is the most commonly used parenteral anticoagulant drug, but it suffers from significant safety and supply issues. Herein, we describe the preparation of heparin mimetic homo- and copolymers via the reversible addition-fragmentation chain transfer (RAFT) polymerization in water of ...
