Description of the thesis topic
Silicones are thermally stable siloxane (Si-O) based polymers and are one of the most important industrial polymers with numerous applications in various fields. The problem of silicone synthesis, since the beginning of industrial silicone production (1943), is the systematic formation of side products (about 15 %), which have to be removed due to their toxicity. During this PhD research program, candidate will try to develop a strategy to solve this problem of silicone synthesis, which has continuously harassed silicone companies without any clear solutions for it. Taking into account the actual large silicon production, the successful development of a new technology, allowing to achieve the production of silicones without any toxic side-products, will provide a huge economic and ecologic gain (Increased yield, avoidance of costly and time-consuming purification process). We will address this important issue by developing new efficient catalytic systems, collaborating with a group of INSA-Lyon and Elkem which is one of the most important companies for the silicone production.
1-The design and the synthesis of suitable efficient organic catalysts for ring-opening polymerization (ROP) of cyclic siloxanes.
2-The test of ROP using obtained catalysts and optimization of reaction conditions.
The candidate must have a solid background in molecular chemistry (organic and polymer chemistry). Some experience in manipulation of high sensitive species would be appreciated.
This research is conducted in frame of a collaborative research program between two academic Institutions [LHFA-Toulouse (T. KATO) and INSA-Lyon (E. Fleury)] and an industrial partner [Elkem (D. Blanc)], founded by the ANR for a period of 3.5 years (2019-2022).
