From these three building blocks there are three possible types of repeating units in polybutene: derived from 1-butene, 2-butene and isobutylene, respectively and where x, y and z represent various numbers of each repeating unit in one particular molecule of polybutene. To clarify the distinction, polybutene products may have average molecular weights from the hundreds to thousands of grams per mol, but polybutylene type formulations may have average molecular weights in the hundred of thousands to even millions of grams per mol. Caulk and sealants Although polybutene formulations may vary in the molecular weight of the polymers, polybutene refers to the relatively low molecular weight polymers that are liquids at room temperature and pressure. There are two main fields of application: PB-1 is compatible with a wide range of tackifier resins. The CIR has not stated an upper allowable limit.

It is compatible with a wide variety of organic materials, for instance, synthetic hydrocarboon polymers including wax, rosin, asphalt and gum. It is also found processed into toothbrush fibers and false eyelashes, and is used in the keycaps[4] of some high-end computer keyboards because the texture is highly resistant to wear and the plastic is less vulnerable to ultraviolet degradation[5] and discoloration than the conventional ABS alternative. Cis-trans Isomerism Standard viscosities available are 10, 40 and 100 (mm/s at 100). Gum base [2] Compared to PET (polyethylene terephthalate), PBT has slightly lower strength and rigidity, slightly better impact resistance, and a slightly lower glass transition temperature.
