VILLEJUST, France - The R&D Department of Eliokem has set up a new process for manufacturing emulsifier-free controlled nanolatex made by Controlled Radical Polymerization (CRP) in a single reactor using only commercially available reactants.

The CRP technique allows the control of polymer composition, enabling new structures (such as block copolymers), new architectures and the control over functions, giving new properties to the same raw materials that are used in conventional radical polymerization.

Eliokem’s researchers have developed a process that avoids the destabilization of the latex during reversible addition-fragmentation chain transfer (RAFT) radical polymerization in emulsion. The new technology uses a single-reactor strategy, with only commercially available raw materials, to produce a surfactant-free nanolatex containing only controlled polymer. This controlled seed can be used for further synthesis to manufacture emulsions made of controlled polymer under RAFT control.

The new process technology can be a tool to produce new materials with nanotechnologies by making use of the bottom-up approach, such as auto structuring of controlled polymer structures.
