    • A crosslinkable aromatic polyester that contains a combination of biphenyl repeating units and aromatic ester repeating units is provided. The aromatic polyester can be generally soluble or dispersible in certain solvents, which allows for the polyester to be formed into a solution and thereafter formed into a film. The crosslinkable aromatic polyester also contains one or more alkynyl functional groups (e.g., end groups, side-chain groups, pendant groups, etc.), which can function as a crosslinking agent. Because it is generally soluble in certain solvent systems, the aromatic polyester can be readily formed into a film using solution-based techniques (e.g., casting) and then crosslinked to impart a higher degree of heat resistance to the polymer.
    • 提供含有联苯重复单元和芳香族酯重复单元的组合的交联性芳香族聚酯。 芳族聚酯通常可溶于或分散在某些溶剂中,这允许将聚酯形成溶液,然后形成膜。 交联性芳香族聚酯还含有一个或多个可用作交联剂的炔基官能团(例如端基,侧链基团,侧基等)。 因为它通常可溶于某些溶剂体系,所以使用基于溶液的技术(例如铸造),芳族聚酯可以容易地形成膜,然后交联以赋予聚合物更高的耐热性。
