Abstract
The present invention discloses a method for making blended polymers by utilizing fluorophilic inter-polymer associative interactions between perfluorocarbon functional groups attached on the constituent polymers. The method of the present invention is capable of forming blended polymers from otherwise incompatible polymers. Also disclosed are blended polymers obtained by the method thereof. Methods and devices utilizing novel blended polymer of the present invention including chromatography, catalysis, photonic and sensor applications are also provided.

A fluorine containing polymer blend, comprising:
- at least two constituent polymers each functionalized with at least one RF functionality,
- wherein the RF functionality is selected from the group consisting of —(CF2)nCF2H, —CO(CF2)nCF2H, —(CF2)nCF3, —CO(CF2)nCF3, —S(CF2)nCF3, —S—CO(CF2)nCF3, —S—(CF2)nCF2H and —S—CO(CF2)nCF2H, wherein 4≦n≦20, and wherein a spacer group, S, comprises one or more methylenes,
- wherein at least one constituent polymer is incompatible with at least one other constituent polymer before being functionalized with RF and wherein the constituent polymers are held together in the polymer blend via fluorophilic interactions between the added RF functionalities.
