Liquid Polybutadienes

We offer a range of stereospecific, low viscous and unsaponifiable liquid polybutadienes of different chemical compositions which are marketed under the trade name POLYVEST®.

Besides non-functionalized maleic anhydride-functionalized liquid polybutadienes, hydroxyl-terminated liquid polybutadiene is the latest entry to our product range.

Specification range offered:

Non-functionalized grades

  • Grades differ in molar mass and viscosity manufactured by Ziegler-Natta polymerization
  • Viscosity at 20 °C: 700-3,300 [mPa s]

Maleic anhydride-functionalized grades

  • Adducts of linear polybutadiene and maleic anhydride
  • Viscosity at 20 °C: 6,000-61,000[mPa s]
  • Acid number: 70-130 [mg KOH/g]

Hydroxyl-terminated grades

  • α,ω-terminated diol of polybutadiene manufactured by radical polymerization
  • Viscosity at 30 °C: 4,000-5,500 [mPa s]
  • OH-number 44-51 [mg KOH/g]
