Polyurethanes (PUs) are essential in numerous industries due to their versatility and high mechanical strength. However, the limited availability of high-performance aromatic polyols and the recycling of polymers continue to pose challenges. Solution through sustainable polyol synthesisThe researchers developed three different aromatic acetal polyols by a solvent-free polycondensation of aldehydes and diols using acidic heterogeneous catalysts. EC Short Course: Waterborne high performance coatingsOn March 18, 2025 the EC Short Course on waterborne high-performance coatings will take place online. The new method could help to make the material cycle for high-performance polyurethanes more sustainable and expand future applications in a wide range of industries.
