Product Description

What is Poly(acrylonitrile-co-methyl acrylate)?

This is a copolymer combining acrylonitrile (the dominant component, ~94 wt.%) with methyl acrylate, produced by copolymerizing the two monomers. The high acrylonitrile content gives the resulting polymer a hydrophobic character and mechanical properties suited to fiber and membrane applications.

Uses of Poly(acrylonitrile-co-methyl acrylate)

This copolymer’s most notable application is in fabricating multilayer mixed-matrix membranes used for efficient separation of ethanol from ethanol-water mixtures — relevant to biofuel and solvent-recovery manufacturing. It also serves as a specialty polymer in acrylic-fiber-adjacent research.
