Patent attributes
In one embodiment, we disclose hardened olefin waxes and processes for preparing them. In another embodiment, we disclose oxidized olefin waxes having low viscosity and processes for preparing them. The waxes are suitable for use as polishes, coatings, or inks, among other uses. For example, a hardened olefin wax composition produced from a feedstock olefin wax composition by contacting the feedstock olefin wax composition with an oxygen-containing gas at a temperature greater than a melting point of the feedstock olefin wax composition, the hardened olefin wax composition having: a needle penetration value at 25° C. at least 5 percent less than a needle penetration value at 25° C. of the feedstock olefin wax composition; a a kinematic viscosity at 100° C. of up to about 200% greater than the kinematic viscosity of the feedstock olefin wax composition; and a saponification number less than 5 mg KOH/g hardened olefin wax composition.
