Kéntartalmú polimerek szintézise invert vulkanizációval nagykapacitású szilárdfázisú akkumulátorokhoz
Title: Kéntartalmú polimerek szintézise invert vulkanizációval nagykapacitású szilárdfázisú akkumulátorokhoz
Copolymerization methods, like inverse vulcanization [1] have gained significant interest in the last decade. Inverse vulcanization, a solvent-free process that enables the synthesis of low-cost materials has great potentials in the field of Li-sulfur batteries [2].
The amount of sulfur determines the capacity in the polymer. Our aim was to prepare polymers with increased sulfur content using low molecular weight hydrocarbons (C7). In this research work, a solvent-free process, norbornene as an organic component and sulfur (S8) were selected for investigating this possibility. The elemental sulfur is an invaluable coproduct and norbornene is also a low-cost product in oil industry [3].
In this presentation, we will focus on the inverse vulcanization process with norbornene and elemental sulfur, the preparation, characterization (1H and 13C NMR, GPC, etc.) of the novel polymer was also carried out. We have optimized the conditions to increase the yield of the polymer and successfully recirculate the coproducts to achieve the polymers in high yields and purity.
