Title: Joseph G. Santangelo: Innovator in High-Temperature Polymer Technologies
Introduction
Joseph G. Santangelo is a notable inventor based in Allentown, PA (US). He holds a total of 8 patents that showcase his expertise in the field of high-temperature polymers. His innovative work has significantly contributed to advancements in polymer technology.
Latest Patents
Among his latest patents is a method for foaming high-temperature polymers using poly(alkylene). This process involves producing cellular foamed articles from high-temperature engineering polymers by utilizing polymeric blowing agents to expand the polymers. The method includes mixing a first polymer capable of being foamed with a second polymer that comprises at least one poly(alkylene carbonate). The process entails heating the polymer blend to a temperature sufficient to melt the polymer and decompose the second polymer to form gas inclusions within the first polymer. The melted first polymer is then expanded to create a foamed article, which is subsequently cooled below its melting or softening point. The polymers that can be foamed through this process are those that can withstand processing temperatures exceeding 260°C. Additionally, he has developed a CO₂ copolymer binder for forming ceramic bodies, which involves a method for making and shaping a green body of ceramic powder.
