Solvent resistant polymers
Central Michigan University
posted on 06/22/2009
High molecular weight polyamines with aromatic nitro groups with exceptional solvent resistance.
Suggested Uses
Coating on metal, solvent resistant adhesives, filter elements
Advantages
Insoluble in all common organic solvents
Dissolves in concentrated sulfuric, nitric, and perchloric acid only
Detailed Description
Due to the presence of inter-chain hydrogen bonding between the secondary amine and the nitro groups, these polymer exhibit exceptional solvent resistance. They can be dissolved only in aqueous concentrated mineral acids with bulky counterions including sulfuric, nitric and perchloric. Melting points range from 100 to 150 deg C.
Limitations
Melting points range from 100 to 150 deg C.
