高氟化弹性体;HIGHLY FLUORINATED ELASTOMERS

摘要

本文描述一种过氧化物可固化、高氟化弹性体，其衍生自(a)下式I之氟化二碘基醚化合物：Rf-CF(I)-(CX2)n-(CX2CXR)m-O-R”f-Ok-(CXR’CX2)p-(CX2)q-CF(I)-R’f;其中X系独立选自F、H、及Cl；Rf及R’f系独立选自F及具有1至3个碳之单价全氟烷；R为F，或部分氟化或全氟化且包含1至3个碳的烷；R”f为具有1至5个碳的二价氟伸烷基或具有1至8个碳与至少一个醚键联的二价氟化伸烷基醚；k为0或1；并且n、m、及p系独立选自0至5之整数，前提是当k为0时，n加m为至少1且p加q为至少1；以及(b)氟化单体。; Rfand R’fare independently selected from F and a monovalent perfluoroalkane having 1-3 carbons; R is F, or a partially fluorinated or perfluorinated alkane comprising 1-3 carbons; R”fis a divalent fluoroalkylene having 1-5 carbons or a divalent fluorinated alkylene ether having 1-8 carbons and at least one ether linkage; k is 0 or 1; and n, m, and p are independently selected from an integer from 0-5, with the proviso that when k is 0, n + m is at least 1 and p + q is at least 1; and (b) a fluorinated monomer.
