摘要： Disclosed are novel polyamideimide elastomers obtained by reaction of carboxyl-telechelic polymer(s) having a molecular weight of 500 to 10,000, aromatic diisocyanate(s), trimellitic acid anhydride and a dicarboxylic acid having 4 to 18 carbon atoms in a particular proportion. The polyamideimide elastomers have excellent heat resistance, oil resistance and low temperature characteristics and have mechanical properties which are comparable to those of polyurethane elastomers. Further, the said elastomers have a particular characteristic that they may retain a rubber-like property even at a high temperature.
摘要翻译： 公开了通过特定比例的分子量为500〜10,000的羧基 - 遥爪聚合物，芳族二异氰酸酯，偏苯三酸酐和具有4〜18个碳原子的二羧酸反应得到的新型聚酰胺酰亚胺弹性体。 聚酰胺酰亚胺弹性体具有优异的耐热性，耐油性和低温特性，并具有与聚氨酯弹性体相当的机械性能。 此外，所述弹性体具有甚至在高温下也可以保持橡胶状特性的特殊特征。
