A revolutionary process for production of polyester resins, for use as polyols in polyurethane manufacture, is claimed by Baxenden Chemicals.
The resins, which are called Xenols, are based on conventional raw materials such as adipic acid, 1,4-butanediol and 1,6-hexanediol, but they are synthesized at room temperature using an enzyme process which mimics a polyaddition type of reaction, producing resins with novel properties.
They have an extremely narrow molecular weight distribution and show sharply improved resistance to hydrolysis.
They are particularly suitable as the polyol component in manufacture of thermoplastic polyurethanes, moisture-curing adhesives and ...
