Latest Patents

Lutz D Zabel holds a patent for "Compounds having one or more aldimine and oxazolidine groups." This patent describes new compounds that contain one, two, or three aldimine groups and one, two, or three oxazolidine groups in their molecular structure. These compounds act as curing agents for organic polyisocyanates. The mixtures of these new compounds with polyisocyanates remain stable for extended periods in the absence of humidity. However, upon contact with water or environmental humidity, they rapidly cure, resulting in elastic or hard polymers. The preparation of these new compounds involves reacting a diamine or polyamine with up to six amino groups with an epoxy compound, yielding a polyamino alcohol. This intermediate is then reacted with an aldehyde, such as formaldehyde or other aliphatic, cyclic, heterocyclic, or aromatic aldehydes.
