Synthesis of Polymeric Nanoparticles by Reversible Addition-fragmentation Chain Transfer (raft) Polymerization in Co2-induced Miniemulsion

Implementation of controlled/living radical polymerization in miniemulsion (typically with oil droplet diameter of 20-500 nm) for synthesis of well-defined, polymeric nanoparticles is of particular interest as miniemulsions possess the inherent advantage that ideally each monomer droplet is transformed into a polymer particles(Zetterlund et al., 2008). However, the high energy requirement for m...

Ultra-fast microwave enhanced reversible addition-fragmentation chain transfer (RAFT) polymerization: monomers to polymers in minutes.

Microwave mediated RAFT polymerization leads to ultra-fast polymerizations, whilst keeping excellent control over molecular weights and molecular weight distributions; this is the first example of such a dramatic effect of microwaves on living radical polymerization kinetics, and it shows the potential for chemists to produce very well controlled polymers in a matter of minutes.

Reversible addition fragmentation chain transfer (RAFT) polymerization from unprotected cadmium selenide nanoparticles.

Reversible addition-fragmentation chain transfer polymerization in microemulsion.

This tutorial review first details the uncontrolled microemulsion polymerization mechanism, and the RAFT polymerization mechanism to provide the necessary background for examining the RAFT microemulsion polymerization mechanism. The effect of the chain transfer agent per micelle ratio and the chain transfer agent aqueous solubility on the RAFT microemulsion polymerization kinetics, polymer mole...

Cryoprotective properties of completely synthetic polyampholytes via reversible addition-fragmentation chain transfer (RAFT) polymerization and the effects of hydrophobicity.

A completely synthetic polyampholyte cryoprotectant was developed with cationic and anionic monomers by reversible addition-fragmentation chain transfer polymerization. The neutralized random polyampholyte, which had an equal composition ratio of monomers, showed high cryoprotective properties in mammalian cells. Introduction of a small amount of hydrophobic monomer enhanced cell viability afte...
