摘要： Polytetramethylene ether glycol is modified so that it contains 1-25%, by weight of β,β'-dihydroxyalkyl sulfide moieties.
These modified polytetramethylene ether glycols have enhanced resistance to degradation by heat and oxygen. The invention also relates to a method of making the modified PTMEG's, to their use as stabilizers against the degradation of the polyether chain, and to polyurethanes made with them.摘要翻译： 四亚甲基醚二醇改性所以没有它含有1-25％（重量）的β，β-二羟基分钟硫化物部分的。 这些改性的聚亚丁基醚二醇已通过热和氧增强的抗降解性。 因此本发明涉及一种制备经修饰的PTMEG的它们作为对抗聚醚链的降解的稳定剂使用的方法，并与它们制成的聚氨酯。
