Vertellus has a long history of supplying polyisobutenyl succinic anhydride (PIBSA) and its derivatives under confidential manufacturing agreements. PIBSAs, manufactured via the thermal process, and their derivatives are custom manufactured in a purpose-built multi-product unit. A range of polyisobutene (PIB) molecular weights can be accommodated to produce a wide variety of PIBSA products.

These PIBSAs can then be further reacted to provide functional and performance products used in the oil, fuel, lubes, mining, coatings, personal care, pigments, dyes, and polymers sectors. A key part of Vertellus’ technology is the amination of the anhydride group of the PIBSA molecule with long-chain polyamines such as DETA, TETA and TEPA. This succinimide formation is carried in 25m3 vessels, affording excellent economies of scale to exacting specifications.


  • Customized production and service to meet customer’s needs
  • Plant capability to make PIBSA/PIBSI and derivatization at one site in order to provide efficiency and cost savings
  • Superior filtration capability and high viscosity handling ability
  • Flexible production size and scheduling


Food Colorant

2-Vinylpyridine is the key intermediate in the production of the API, betahistine, an anti-vertigo medicine.

2-Vinylpyridine is a reactive monomer and once polymerized, the nitrogen is less exposed/accessible than its counterpart, 4-Vinylpyridine. It can be copolymerized with many other monomers, in particular cationic monomers, such as acrylamide, acrylates, and also with other vinyl-based monomers (e.g. styrene). The benefit of the addition of a 6-membered heterocyclic moiety is the increased Van der Waals forces which impart better electrostatic forces to the finished polymer, improving adhesion.
