  • Oxidized alpha-olefins
    Patent number: 4426229
    Abstract: In contrast to hydrocarbon waxes, alpha-olefin waxes can be oxidized with little if any reduction in hardness. The oxidized product can be used as such or further reacted with polyisocyanates to yield isocyanated products. Salts of the isocyanated products (preferably lithium salts) are also prepared which are capable of forming colloidal solutions. These solutions preferably in hydrocarbons have superior film-forming properties when used in polishes, thus yielding when applied to a surface a finish of high gloss, durability, protection, etc. The isocyanated products and salts thereof when employed in carbon paper inks yield a carbon paper having superior properties.
