Latest Patents

Dale Hunter's latest patents include a process for making polymer polyol having monodisperse dispersed polymer particles. This innovative process involves the polymerization of styrene and acrylonitrile in the presence of a base polyol, a seed dispersion, and a solvent. The resulting polymer polyol features dispersed phase particles with a size of 1 to 3 µm and a particle size span of less than 1.25. These polymer polyols are particularly useful for creating flexible polyurethane foam, which is essential for applications requiring high airflows and good load-bearing capabilities.

Another significant patent by Hunter is related to PIPA polyol-based viscoelastic foams. This foam is produced by reacting an isocyanate compound with water and a polyol mixture. The polyol mixture consists of a dispersion of polyurethane or polyurethane-urea particles in a carrier polyol (a PIPA polyol) along with at least one other polyol. The resulting viscoelastic foams are characterized by high airflows and long recovery times, making them suitable for various applications.
