Latest Patents

Hoffman's most notable patent involves the production of radiation-curable phenoxy resins. The patent describes a unique reaction product created by combining an adduct of an ethylenically unsaturated monohydric alcohol, such as 2-hydroxyethyl acrylate, with an organic diisocyanate. This process ensures the absence of unreacted diisocyanate by using the alcohol in a molar excess. The resulting phenoxy resin is a high molecular weight hydroxy functional polyether, which is instrumental in creating unsaturated products that are particularly useful in electron beam coating compositions.
