RAFT polymerization uses commercial agents to control polymer properties without cytotoxic heavy metals like ATRP.

RAFT polymerization offers living characteristics to radical polymerization, contributing versatility to reversible deactivation radical polymerization methods.

Over the past two decades, the rapid advance of controlled living polymerization (CLP) techniques.

The modification of biomacromolecules, such as peptides and proteins, through the attachment of synthetic polymers has led to a new family of highly advanced biomaterials with enhanced properties.

Protocols

RAFT polymerization offers precise control, enabling tailored synthesis of complex polymer structures.

We present an article about RAFT, or Reversible Addition/Fragmentation Chain Transfer, which is a form of living radical polymerization.

We presents an article featuring procedures that describe polymerization of methyl methacrylate and vinyl acetate homopolymers and a block copolymer as performed by researchers at CSIRO.

Polymerization via ATRP procedures demonstrated by Prof. Dave Haddleton's research group at the University of Warwick.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
