Polyisobuteneamine (PIBA) is a polymer derived from the reaction of polyisobutylene (PIB) with ammonia or primary amines.
This polymeric compound is known for its excellent adhesive and dispersant properties and is commonly used as an additive in lubricants, fuel, and other industrial applications.
The first synthesis of polyisobutylene was reported in 1931 by the German chemists Hermann Staudinger and Leonidas Zechmeister, who obtained the polymer through the cationic polymerization of isobutylene.
It has excellent adhesion and dispersant properties, which are attributed to its polar amine groups and nonpolar polyisobutylene backbone.
[2] The unique combination of polar and nonpolar groups allows PIBA to interact with a wide range of materials, making it a versatile additive.
