POLYVEST®<br />
Designed Polymers for <strong>Adhesive</strong>s & Sealants<br />
Liquid Polybutadienes<br />
With its POLYVEST® <strong>Evonik</strong> offers a range of stereospecific, low viscous and<br />
unsaponifiable liquid polybutadienes of different chemical composition:<br />
• POLYVEST® - non-functionalized liquid polybutadienes<br />
• POLYVEST® MA - maleic anhydride-functionalized liquid polybutadienes<br />
• POLYVEST® HT - hydroxyl-terminated liquid polybutadienes<br />
Our non-functionalized products differ in molar mass and viscosity.<br />
The MA-functionalized products are adducts of linear polybutadiene and maleic<br />
anhydride and differ in maleic anhydride content and viscosity. The anhydride<br />
groups are randomly distributed along the polymer chains and thus make the<br />
originally apolar polybutadiene more polar and accessible for various chemical<br />
reactions.<br />
The hydroxyl-terminated product is an alpha-omega-terminated diol of<br />
polybutadiene manufactured by radical polymerisation process. In addition to the<br />
double bonds in the polymer backbone, the hydroxyl functional groups provide<br />
opportunities for precise chemical modifications.<br />
The non-functionalized POLYVEST® grades are supplied in steel drums with<br />
190kgs net. The maleic anhydride-functionalized grades are supplied in steel drums<br />
with 180kgs net and 900kgs net IBC. POLYVEST HT® is available in steel drums<br />
and IBC. Road tanker delivery is possible for all grades.<br />
Your benefits<br />
The microstructure of our POLYVEST® grades makes them a highly reactive<br />
and cross-linking binder and provides them with properties including:<br />
• excellent chemical resistance<br />
• high water resistance<br />
• very good electrical insulation<br />
• very good cold-resistance<br />
• low moisture and oxygen permeability<br />
Our POLYVEST® grades can be used in a broad field of applications.<br />
