摘要： This disclosure is directed to crosslinked thermoplastic polyurethane elastomers that include allyl ether side groups in the urethane structure, specifically in the hard segments of the polyurethane polymer, and a free radical source. This disclosure is also directed to methods of synthesizing the crosslinked thermoplastic polyurethane elastomers having allyl ether side groups in the hard segments. The solvent resistance, water resistance, weather resistance, and heat resistance are improved as a result of the urethanes elastomers being prepared according to this disclosure. As a result of these improved properties, the finished crosslinked polyurethane elastomers can be applied in articles such as footwear parts or soles, tubes, hoses, cables, films and sheets.

摘要翻译： 本公开涉及在聚氨酯结构中包括烯丙基醚侧基的交联热塑性聚氨酯弹性体，特别是聚氨酯聚合物的硬链段和自由基源。 本公开还涉及在硬链段中合成具有烯丙基醚侧基的交联的热塑性聚氨酯弹性体的方法。 作为根据本公开制备的聚氨酯弹性体的结果，耐溶剂性，耐水性，耐候性和耐热性得到改善。 作为这些改进的性能的结果，成品交联的聚氨酯弹性体可以应用于诸如鞋类部件或鞋底，管，软管，电缆，薄膜和片材的制品中。
