FLUOROETHER UNIT-BASED THERMOSTABLE, LOW-TG AND THERMOSETTING CROSS-LINKED MATERIALS

The present invention relates to a cross-linkable composition comprising: i) a fluorinated alpha,omega-bis(propargyl) oligomer of formula (I): in which m is 1 to 100, e.g. 1 to 93, n is 2 to 150, e.g.1 to 128, p is 0 to 2, preferably 0 or 1.75, and n, m and p are selected such that the fluorinated alpha,omega-bis(propargyl) oligomer of formula (I) has a number average molar mass Mn of 400 to 25000; ii) a cross-linking agent comprising at least three azide-N3 groups; and iii) optionally, a fluorinated oligomer comprising two terminal azide-N3 or fluorinated alpha,omega-bis(azide) oligomer groups. The invention also relates to a material comprising the click chemistry reaction product of the cross-linkable composition of the invention, to a method for preparing said material and to the usesthereof. 本发明涉及种交联组合物，该交联组合物包括：式(I)的氟化α,ω-双(炔丙基)低聚物：其中，m为1至100，例如1至93，n为2至150，例如1至128，以及p为0至2，优选0或1.75，所选择的n、m和p使得所述式(I)的氟化α,ω-双(炔丙基)低聚物具有400至25000的数均摩尔质量M；ii)含至少三个叠氮基-N的交联剂；以及iii)可选地，含两个末端叠氮基-N的氟化低聚物或者氟化α,ω-双(叠氮基)低聚物。本发明还涉及种含
