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.
Polyisobutene (polyisobutylene) is a class of organic polymers prepared by polymerization of isobutene. The polymers often have the formula Me 3 C[CH 2 CMe 2] n H (Me = CH 3). They are typically colorless gummy solids. Cationic polymerization, initiated with a strong Brønsted or Lewis acid, is the typical method for its production.
When used as an additive in lubricating oils and motor fuels, they can have a substantial effect on the properties of the oil or fuel. [3] [4] Polyisobutylene added in small amounts to the lubricating oils used in machining results in a significant reduction in the generation of oil mist and thus reduces the operator's inhalation of oil mist.

Isobutylene is used in the production of a variety of products. It is alkylated with butane to produce isooctane or dimerized to diisobutylene (DIB) and then hydrogenated to make isooctane, a fuel additive. Isobutylene is also used in the production of methacrolein. Polymerization of isobutylene produces butyl rubber (polyisobutylene or PIB).
ASAs are related to the class of polyisobutylenylsuccinic anhydrides, known as PIBSAs. In these compounds, the alkene used is polyisobutylene. Such compounds are commonly used as reactive intermediates in the petroleum additive industry.
Here’s what to know about some of the most controversial food additives under the microscope and why additives are regulated differently in the U.S. Key ingredients banned in Europe but allowed ...
Polybutene is an organic polymer made from a mixture of 1-butene, 2-butene, and isobutylene.Ethylene steam cracker C4s are also used as supplemental feed for polybutene. It is similar to polyisobutylene (PIB), which is produced from essentially pure isobutylene made in a C4 complex of a major refinery.
The FDA determined that the data presented in a 2022 color additive petition show that this ingredient causes cancer in male laboratory rats exposed to high levels of FD&C Red No. 3 because of a ...
