Silicones without cyclic compounds - Towards safe and robust soft-materials – SILISCY

Submission summary

Silicones, or polydiorganosiloxanes, are polymers having outstanding performances and great versatility in uses. During their synthesis, some cyclic oligosiloxanes are obtained by a retro-sission side reaction. The presence of these cyclic oligosiloxanes limits the application range of silicones.

Taking these considerations into account, the aim of the project SILISCY is to develop new efficient catalysts, easily deactivable or removable that, associated to a specific polymerization process, would lead to the synthesis of silicones having a high degree of purity, without cyclic compounds. To achieve this objective, the SILISCY project is based on a multi-competencies team, located in Elkem Silicones France, LHFAteam in Toulouse, and IMP team in Lyon. The proposed methodology is fully described in the attached scientific file.

The success of this project will lead to soft materials safe and robust, which will significantly enlarge the application range of silicones.
