What is the Difference Between Isobutylene and Polyisobutylene?
🆚 Go to Comparative Table 🆚The principal difference between isobutylene and polyisobutylene lies in their structure and properties:
- Isobutylene: It is a monomer, meaning it is a single molecule that can be combined with other similar molecules to form a polymer. Isobutylene is a colorless, flammable gas with the chemical formula CH3CH2CH=CH2.
- Polyisobutylene: Also known as polyisobutene or PIB, it is a polymer made from the polymerization of isobutylene. Polyisobutylene is a vinyl polymer that is similar in structure to polyethylene and polypropylene, except that every other carbon is substituted with two methyl groups. It is a colorless, gummy solid and has various applications, including adhesives, plasticizers, and butyl rubber.
In summary, isobutylene is a monomer that serves as the building block for polyisobutylene, which is a polymer with a wide range of applications in different industries.

The key difference between isobutylene and polyisobutylene is that isobutylene is a monomer, whereas polyisobutylene is a polymer. Here is a summary of their differences in a table:
Property | Isobutylene | Polyisobutylene |
---|---|---|
Definition | Isobutylene is an organic compound with the chemical formula CH3CH2CH=CH2. | Polyisobutylene is an organic polymer made from the polymerization of isobutylene. |
Structure | Isobutylene appears as separate, individual molecules. | Polyisobutylene molecules contain numerous isobutylene molecules connected to each other. |
Molecular Weight | Isobutylene has a molecular weight of approximately 58.1 g/mol. | Polyisobutylene has a molecular weight that varies depending on the polymerization process, ranging from low to high molecular weight. |
Applications | Isobutylene is mainly used in the production of polyisobutylene and other polymers. | Polyisobutylene has various applications, including use as a plasticizer, gas additive, and in pressure-sensitive adhesives. |
Both isobutylene and polyisobutylene are important materials in the chemical industry, with isobutylene being a building block for the synthesis of polyisobutylene and other polymers.
