What is the raw material for polyisobutylene?
Polyisobutylene (PIB) is a synthetic polymer created through the polymerization of isobutylene, a byproduct of petroleum refining and hydrocarbon cracking. Isobutylene is separated and purified to create PIB molecules, and catalysts can be used to obtain HR-PIB grades.
How Is Polyisobutylene (CAS 9003-27-4) Made?
Polyisobutylene (CAS 9003-27-4) is made from the monomer isobutylene, by cationic vinyl polymerization. Polyisobutylene is a synthetic rubber, or elastomer. It's special because it's the only rubber that's gas impermeable.
Is polyisobutylene soluble in water?
Polyisobutylene (PIB) is the polymer of isobutene, the main component of butyl rubber. One of the most important properties is its solubility in water. This property makes the product group to a universally usable polymer, for a variety of different industrial applications.
