Polyisobutylene (PIB) is a polymer made from isobutylene by cationic polymerization, and its molecular weight can range from hundreds to millions. It is a typical saturated linear polymer, the main body of the molecular chain does not contain double bonds, no long branches exist, and the structural unit is -(CH2-C(CH3)2)-.
Physical and chemical properties of polyisobutylene
Polyisobutylene is a colorless, transparent or light yellow viscous liquid, non-toxic, odorless and non-irritating. Its physical and chemical properties are stable, and it has good thermal stability and storage stability. The specific gravity of polyisobutylene is 0.822 at 20°C, the refractive index is 1.457, the melting point does not exceed -50°C, the acid value and saponification value are low, and the iodine value is also low.
Application fields of polyisobutylene
Polyisobutylene is widely used in many industries such as lubricants, adhesives, and cosmetics. For example, highly active polyisobutylene is mainly used in lubricants and adhesives, while Polybutene-1000 is used in the oil phase components of cosmetics and medicines, and has the characteristics of moisturizing, lubrication and strong permeability.
