Polyether amines are a family of specialty polymers characterized by a polyether backbone, typically composed of repeating propylene oxide, ethylene oxide, or mixed oxide units, with reactive amine groups (primary or secondary) attached at one or both ends of the molecular chain. This unique chemical structure combines the flexibility, low viscosity, and hydrophilicity (or hydrophobicity, depending on the backbone) of polyether chains with the high reactivity of amine groups. They are often referred to by trade names such as JEFFAMINE® and are produced through processes like the amination of polyether polyols. The functional versatility of polyether amines is a result of their tunable nature; by selecting different backbones and molecular weights (which range from around 200 to 5000 g/mol), manufacturers can create products with tailored properties, from high-reactivity diamine curing agents to monoamines that act as effective surfactants.
Due to this versatility, polyether amines serve as critical performance additives across…
