Your skills

The candidates must hold a Master degree and have experience in polymer chemistry (preferably free radical polymerization) and/or physico-chemistry of polymer colloids. A strong command of written and spoken English is necessary.

Your responsibilities

In the context of this project, a latex is a stable, homogeneous dispersion of submicron polymer particles in a continuous aqueous phase obtained by emulsion polymerisation. A latex presents different advantages: the low viscosity of the dispersion makes the product easy to manipulate; the reaction mechanisms involved in emulsion polymerisation allow us to reach very high molecular weight and low amounts of residual monomer; the continuous medium is water, which is non-polluting and relatively inexpensive; the use of water as the continuous phase makes it easier to remove the heat generated by the reaction than in solution polymerisation. It is for these reasons, as well as many others, that emulsion process is widely used and that latex applications are diverse and numerous.

For several reasons it is interesting to reach high polymer concentrations in latex. First, from a productivity point of view, higher latex solid content allows for the production of higher amounts of polymer per production line and makes latex treatment section more efficient by reducing the time and energy required for drying. Also, in some applications, increasing the polymer content can improve certain properties, e.g. by reducing the drying time or by enhancing the quality of one coat of film. It also helps to lower certain costs, such as transportation and storage.

The C2P2 group has been doing extensive research in the chemistry and engineering of aqueous emulsion polymerizations for over 30 years. Relying on the expertise of the C2P2 in polymerization in dispersed media, the aim of the present project is the identification and understanding of key technical levers that would allow us to increase the final solid content of industrial latex. The project will be developed in the frame of an industrial collaboration with Arkema (CIFRE funding).
