Polybutene is synthetic hydrocarbon polymers made by polymerization of C4 olefins (primarily isobutene) and are available in a wide range of viscosities. By controlling the polymerization conditions, polymer chains of different lengths are manufactured giving a wide range of polybutene grades having different physical properties. Short chain-length polybutenes are free-flowing; medium chain-length polybutenes are sticky with a honey-like consistency, while those with the longest chain length are very tacky, semi-solid materials.
