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.

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.
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).
Polyolefin sheets or foams are used in a wide variety of packaging applications, sometimes in direct contact with food. [14] Polyolefin elastomer POE is used as a main ingredient in the molded flexible foam technology such as in the fabrication of self skinned footwear (for example, Crocs shoes), seat cushions, arm rests, spa pillows, etc ...
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.
It is also used synergistically as a blend element to modify the characteristics of other polyolefins like polypropylene and polyethylene. Because of its specific properties it is mainly used in pressure piping, flexible packaging, water heaters, compounding and hot melt adhesives.
Food processing residuals are often referred to as FPRs. Treatment sludges, bones and feathers from slaughterhouses, and refuse from fruits and vegetables are among the common forms.
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.
