    摘要： To provide a crosslinkable fluorinated aromatic prepolymer which is capable of forming a cured product having high transparency, a low relative permittivity, high heat resistance, low birefringence and high flexibility, and its uses.
    A crosslinkable fluorinated aromatic prepolymer which is obtained by subjecting a compound (Y-1) having a polymerizable double bond (A) and/or a phenolic hydroxyl group and a compound (Y-2) having a polymerizable double bond (A) and a fluorinated aromatic ring, to a condensation reaction in the presence of a HF-removing agent, with a fluorinated aromatic compound (B) represented by the following formula (1):

    (wherein n is an integer of from 0 to 3, each of a and b which are independent of each other, is an integer of from 0 to 3, and each of Rf 1 and Rf 2 is a fluorinated alkyl group having at most 8 carbon atoms), and a compound (C) having at least 3 phenolic hydroxyl groups, the respective phenolic hydroxyl groups not being present in the same aromatic ring, and which has polymerizable double bonds (A) and ether bonds and has a number average molecular weight of from 1×10 3 to 5×10 5 .
