General description

PiBMA can be prepared by free radical polymerization.[1]

Application

Binder in plastic coatings, aerosol paints, primers and printing inks
Glycidyl methacrylate grafted poly(isobutyl methacrylate) (PiBMA) microbeads can be used as super adsorbent beads for adsorption of heavy metal ions such as uranyl ions from aqueous solutions.[2] A study reports its use in the fabrication of polymer/polymer nanocomposites.[1]
