Latest Patents

John A. Rice holds a patent for a "Method for forming composite simulated ivory materials." This invention involves a family of composite materials that consist of a mineral filler and a synthetic polymer, characterized by properties similar to natural ivory. The composite material contains approximately 25 to 75 percent by weight of the mineral filler, preferably calcium phosphate, and about 75 to 25 percent by weight of a polyamino acid, such as poly(gamma-methyl L-glutamate). The method employs in situ polymerization techniques to ensure a homogeneous blend of the mineral and polymer phases, allowing for easy preparation at ambient temperatures. The resulting ivory-like composite can be molded into various shapes for decorative or practical applications.
