Latest Patents

One of Juang's latest patents is titled "Process for manufacturing polyurea microcapsules and product therefrom." This patent describes two embodiments of a process for producing concentrated suspensions of polyurea microcapsules, which are especially suitable for manufacturing carbonless copy paper (CCP). The first embodiment involves emulsifying a liquid hydrophobic phase with an aqueous continuous phase to form a suspension of microdroplets. A polyamine, such as diethylenetriamine, is then added to initiate an interfacial polyaddition reaction, resulting in the formation of polyurea microcapsules. The second embodiment is similar but includes the addition of a surfactant with multiple S-containing substituent groups. The microcapsules produced exhibit excellent impermeability, resistance to agglomeration, and storability, making them ideal for use in CCP.
