General description

Poly[(isobutylene-alt-maleic acid, ammonium salt)-co-(isobutylene-alt-maleic anhydride)] (PIM) is a water soluble polymer.

Application

Binder for ceramic powders and dispersing agent for water soluble paints.
PIM may be used to prepare montmorillonite (MMT) clay and amylopectin-based nanocomposites. PIM may be used as a dispersant for the preparation of NiO/Y3O3-ZrO2 for solid oxide fuel cells (SOFCs). PIM may also find use as a coupling agent.Binder for ceramic powders and dispersing agent for water soluble paints.
