Poly(propylene glycol) bis(2-aminopropyl ether) Usage And Synthesis

Description

Amine-TerminatedPolyether (ATPE) is a class of polyolefin compounds with a soft polyether backbone, capped by primary or secondary amine groups. Because the main chain of the molecule is a soft polyether chain, and the hydrogen on the terminal of polyether amine is more active than the hydrogen on the terminal hydroxyl group of polyether, therefore, polyether amine can be a good substitute for polyether in some material processes, and can improve the application performance of new materials. They are widely used in polyurethane reactive injection molding materials, polyurea spraying, epoxy resin curing agents and gasoline scavengers.

Chemical Properties

Poly(propylene glycol) bis(2-aminopropyl ether) is a light yellow or colorless transparent liquid at room temperature, with the advantages of low viscosity, low vapor pressure and high primary amine content, and is soluble in solvents such as ethanol, aliphatic hydrocarbons, aromatic hydrocarbons, esters, glycol ethers, ketones and water.

Uses

Poly(propylene glycol) bis(2-aminopropyl ether) have good alkali and water resistance and moderate acid resistance. Epoxy resins cured with polyetheramines have good electrical properties. Polyetheramines have unique properties and are used in almost all epoxy applications such as coatings, potting materials, construction materials, composites and adhesives.

Preparation

synthesis of Poly(propylene glycol) bis(2-aminopropyl ether): Firstly, the polyether is attached to the acetoacetate group at both ends by dienone or through the ester exchange reaction of ethyl acetoacetate with polyether polyol, and then the polyether capped by the acetoacetate group is aminated with a mono-primary amine, alkyl alcohol amine or dibasic primary amine to obtain an imine compound with a low viscosity with an aminobutyrate end group.
