采用溶液缩聚法合成了含有2,5-二（4-氟苯甲酰）苯并环丁烯（BFBCB）、1,4-二（4-氟苯甲酰）苯（BFB）和4,4-异丙基二酚的高分子量共聚物。在温度保持在150℃以下的条件下，得到了可溶的无定形聚合物，并且在聚合反应中没有发生交联的迹象。通过在400°C的氮气中短暂处理，聚合物可以交联远高于其T g。所得的网络在所有溶剂中都不溶。交联反应没有明显的质量损失
High molecular weight copolymers containing 2,5-bis(4-fluorobenzoyl)benzocyclobutene (BFBCB),1,4-bis(4-fluorobenzoyl)benzene (BFB), and 4,4-isopropylidenediphenol have been synthesized by solution polycondensation. Soluble, amorphous polymers were obtained and no evidence of cross-linking occurred during the polumerization reaction, provided that the temperature was maintained below 150°C. The polymers can be cross-linked well above their T g by brief treatment in nitrogen at 400°C. The resulting networks are insoluble in all solvents. No significant mass loss accompanies the cross-linking reaction
