Latest Patents

Zang is credited with 1 patent: “Method of Preparing Alkyl Functionalized Polysiloxane.” The method involves reacting a silane oligomer with hydroxyl-terminated polysiloxane in the presence of a first catalyst, then reacting the resulting product with an endcapper in the presence of a second catalyst.

The process is designed to allow flexible adjustment of polymerization degree and viscosity. It can also introduce multiple alkyl functional groups and additional functional groups to produce bifunctionalized polysiloxane. The described benefits include reducing unwanted cyclosiloxanes in the equilibrium product and using mild, environmentally friendly reaction conditions that are easy to operate.
