Technical Bulletin ® JEFFAMINE Polyetheramines Huntsmans JEFFAMINE® range offers the world’s most extensive selection of polyetheramines, many of which are unavailable elsewhere. These highly versatile products contain primary amino groups attached to the end of a polyether backbone normally based on propylene oxide (PO), ethylene oxide (EO), or a mixture of both oxides. Historically, the core JEFFAMINE® polyetheramine family consisted of monoamines, diamines and triamines based on the core polyether backbone structure. More recently, the addition of hindered, high-conversion, and polytetramethylene glycol (PTMEG) based polyetheramines has increased the breadth of utility of the product line. ® The JEFFAMINE polyetheramines typically impart increased flexibility and toughness and are easily handled low viscosity, low color products. The broad range of molecular weights, amine functionality, repeating unit type and distribution offers great scope to design new compounds or mixtures. The amines are particularly important in the production of polyurea coating technologies, epoxy applications and pigment formulations. ® JEFFAMINE Monoamines (M series) ® ® JEFFAMINE monoamines are designated as the JEFFAMINE M series. The letter M signifies a monoamine and the number represents the approximate molecular weight. JEFFAMINE® M series products are prepared by reaction of a mono-alcohol initiator with EO and/or PO, followed by conversion of the resulting terminal hydroxyl groups to amines. M series products have the following representative structure: JEFFAMINE® Hydrophilicity MW Amine
