The present invention relates generally to polyimides. It relates particularly to novel polyimides prepared from 2,3,3′,4′-biphenyltetracarboxylic dianhydride and aromatic diamines. These novel polyimides have low color, good solubility, high thermal emissivity, low solar absorptivity and high tensile strength.
本发明涉及聚酰亚胺。尤其涉及从2,3,3′,4′-联苯四羧酸二酐和芳香族二胺制备的新型聚酰亚胺。这些新型聚酰亚胺具有低色差、良好的溶解性、高热辐射率、低太阳吸收率和高拉伸强度。
