Abstract
The invention pertains to a cross-linkable fluorinated polymer comprising the carbonate moiety having formula (I) wherein n=1-10 and m=0-9. Preferably, the polymer further comprises a cross-linkable moiety derived from a diol selected from (II) and (III) wherein A, A , and A are independently a bond or C alkylene, or together with the carbon atoms to which they are bonded form a 5- or 6-membered ring; B is independently O or C alkyl; Q is —CO—C(=E)D, wherein D is H or C alkyl, and E is C alkylidene; and each of the alkyl, alkylene, and alkylidene groups may be halogenated. The polymers of the invention can be used in cladding layers or waveguides, in particular for thermo-optical devices.
