Latest Patents

Donat's latest patents focus on processes that improve the fabrication properties of polyvinyl chloride. One of his key inventions is a method for preparing a low inherent viscosity-high glass transition temperature enhancing agent. This agent improves the melt flow of PVC by treating the resin with a specific enhancing agent. The treatment occurs through a suspension or mass overpolymerization, where at least one high glass transition temperature enhancing agent reacts with a chain transfer agent. This innovative process results in a high glass transition temperature and reduces the inherent viscosity of the PVC resin.

Another significant patent involves the treatment of polyvinyl chloride resins with a low inherent viscosity-high glass transition temperature enhancing agent. This treatment imparts improved processing properties, especially desirable in melt-type fabrication processes such as custom injection molding. The high glass transition temperature-inherent viscosity enhancing agent is produced through polymerization in the presence of a chain transfer agent, resulting in an agent that possesses both high glass transition temperature and low inherent viscosity.
