本发明是关于一个坚韧的热塑性的聚脂生聚■弹性的制备过程。此弹性体在本质上是无关联的结构的在变形以后容易复原,并通过长用具有的熔点。更详细地说:本发明是关于一个弹性的热塑性聚氨酯材料的制备方法,这个材料由一个羟基封端的线型聚酯与一个二苯基二异氰酸脂和一个脂族二醇的反应产物所组成。所说的反映产物是不是有任何一个反
The present invention relates to a tough, thermoplastic, polyadhesive ■ elastomeric preparation process. This elastomer is essentially an unrelated structure that is easily restored after deformation and has a melting point through long use. More in detail: The present invention relates to a process for preparing a flexible thermoplastic polyurethane material consisting of a reaction product of a hydroxyl-terminated linear polyester with a diphenyl diisocyanate and an aliphatic diol composition. Is there any contradiction between the mentioned products?
