ISOBAM™

General name
Isobutylene polymer
Sales format
Powder
Examples

Alkali soluble polymer with excellent characteristics

ISOBAM™ is an alkaline hydrosoluble copolymer of isobutylene and maleic anhydride. In powder form, ISOBAM™ is used as a water soluble polymer reacting with sodium hydroxide, ammonia and amine. Various useful reactants are obtained by the reaction of ISOBAM™ with alcohol, amine and epoxy compounds.

Characteristics

Alkaline water-soluble polymer

Excellent heat resistance compared with other water soluble polymers.

Aqueous solution viscosity varies from acidic to alkaline through control of alkali content.

Different grades are available with aqueous solution viscosity that varies based on different molecular weights.

Solubility and binder performance. Extreme hardness.
