Polytetramethylene ether glycol (PTMEG/PTG) is produced by the acid catalyzed polymerization of tetrahydrofuran (THF). It is a straight-chain diol with repeated tetramethylene ether units.
1,4-Butanediol (BDO) is produced by hydroformylation of allyl alcohol with carbon monoxide and hydrogen, which is then followed by hydrogenation. It is a colorless liquid with high boiling point and low toxicity.
Vinyl acetate monomer (VAM) is a reactive colorless liquid chemical that is produced by gaseous reaction of ethylene, acetic acid, and oxygen in the presence of a catalyst. Hydroquinone is added as a stabilizer to inhibit polymerization during storage.
