ISOBAM
ISOBAM TM is
ISOBAM is a the trade name of a copolymer of isobutylene and maleic anhydride developed by KURARAY CO.,LTD . using its PVA (polyvinyl alcohol) technology.
ISOBAM is an alkali water soluble polymer with outstanding characteristics which have never been attained with conventional water soluble polymers such as polyvinyl alcohol and cellulose derivatives.
ISOBAM is a white powder in appearance , it is generally 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.These can be applied to resins and plastics.

Standard type of “ISOBAM”
Differing from conventional water soluble polymers, ISOBAM is used by reacting with alkali.
These alkali solutions can be easily modulated from low viscosity to high viscosity and from acidity to alkalinity.
Standard type of ISOBAM is used as binders with excellent heat resistance, and hardness.
Also Standard type has an excellent dispersing effect with high functionality of the carboxyl group which is aligned side by side in the molecule
