Latest Patents

Leyrer's latest patents include a process for the production of low viscosity, high functionality, light-colored sucrose-based polyethers. This innovative process involves reacting a starter mixture that contains approximately 100 parts by weight of sucrose, along with a low molecular weight, relatively high valency alcohol and/or an alkoxylation product of such an alcohol. The reaction is facilitated by an alkali metal hydroxide at controlled temperatures and pressures. These polyether polyols are particularly useful for producing rigid polyurethane foams. Another patent focuses on stiff-chain polyheterocycles that exhibit improved solubility in specific solvent mixtures, making them suitable for creating blends with thermoplastic polymers.
