Abstract
The present invention relates to a cross-linkable composition comprising: i) a fluorinated α,ω-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 α,ω-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-Ngroups; and iii) optionally, a fluorinated oligomer comprising two terminal azide-N3 or fluorinated α,ω-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 uses thereof.
