MBM      Monobutyl maleate CAS No. 925-21-3

MMM, MEM and MBM are the half esters of maleic acid. These products provide a carboxylic acid functionality with maleate unsaturation. Therefore, MMM, MEM and MBM provide plasticizing effect, as well as promotion of improved polymer adhesion, due to the carboxylic groups.

They can be copolymerized with a variety of vinyl and acrylic monomers to provide coatings with improved stiffness and adhesion and reduced tackiness or tendency to block.
