WebMar 18, 2024 · Mechanochemistry – the utilization of mechanical forces to induce chemical reactions – is a rarely considered tool for polymer synthesis. It offers numerous advantages such as reduced solvent consumption, accessibility of novel structures, and the avoidance of problems posed by low monomer solubility and fast precipitation. WebSolvents: A solvent is a substance that dissolves a solute to form a homogeneous solution. In chemical reactions, solvents are used to dissolve the reactants, facilitate the reaction, and control the reaction rate. They are essential for many industrial processes, such as the production of pharmaceuticals, polymers, and fine chemicals.
