PERFLUOROETHER UNIT-BASED THERMOSTABLE, LOW-TG THERMOPLASTIC COPOLYMERS

摘要

The present invention relates to a polymerisable composition comprising: i) a fluorinated α,ω-bis(propargyl) oligomer of formula (I): in which m is 1 to 100, n is 2 to 150, p is 0 to 2, e.g. 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; and ii) a fluorinated oligomer comprising two terminal azide-N3 or fluorinated α,ω-bis(azide) oligomer groups. The invention also relates to a thermoplastic copolymer comprising the click chemistry reaction product of the polymerisable composition of the invention, to a method for preparing said copolymer and to the uses thereof.
