Polytetramethylene Ether Glycol Uses

Polytetramethylene ether glycol (PTMEG) is a homopolymer obtained by cationic ring-opening polymerization. PTMEG is a linear polyether glycol with primary hydroxyl groups. At room temperature, PTMEG is a white waxy solid. When the temperature exceeds room temperature, PTMEG is melted into a clear, colorless liquid. PTMEG is readily soluble in alcohols, esters, ketones, aromatic and chlorinated hydrocarbons and insoluble in aliphatic hydrocarbons and water.

1.4-Butanediol

1.4-Butanediol (chemical formula: HOCH2CH2CH2CH2OH) is one of the isomers of butanediol, a terminal dihydroxy substituent of butane, which is a colorless, viscous liquid at room temperature. Industrially, BDO is produced by allowing acetylene to react with two molecules of formaldehyde to form BDO, which is then hydrogenated. BDO can also be obtained by gas-phase hydrogenation of anhydrides.
