JEFFAMINE T-5000 is a 5000 molecular weight polyoxypropylene triamine that can be added to a variety of curing agents to impart flexibility and improve peel strength of the adhesive systems with little degradation in other properties. Usually, secondary amines do not show a band in this region and tertiary amines never show a band in this region. (This band can be very sharp and close enough to the carbonyl region to cause students to interpret it as a carbonyl band.) Another band attributed to amines is observed in the region 910-665 cm -1. Sep 26, 2019 · Among the polyetheramines used as curing agents Polyetheramine D 2000 is by far the most commonly applied product. Addition of Polyetheramine D 230 and D 400 leads to higher reactivity of the curing system and also to harder films. Abstract. Novel polyetheramine-based hydrogels have been synthesized by reacting difunctional Jeffamine of varying molecular weights (ED600, ED900 and ED2003) with glutaraldehyde (GA) in the presence of trifunctional Jeffamine (T403) as a crosslinker. The behavior of the modified Jeffamine in water was first investigated. A direct micellar phase (L(1)) and a hexagonal (H(1)) liquid crystal were found. The structure of the micelles was investigated from the SAXS and the analysis by generalized indirect Fourier transformation, which show that the particles are globular of core-shell type. Overall, the structure- property relationships of ceramers made from these two oligomers are similar. Among the few differences is the tensile stress-strain behavior. The ACCLAIM™ based ceramers can be drawn to higher extents before failure. Also among the discrepancies is the dynamic mechanical behavior in the rubbery region.
