POLYVEST®
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]
