Abstract

Summary: The synthesis and polymerization of novel 18โ€crownโ€6 and 24โ€crownโ€8 bis aryl trifluorovinyl ethers is described. Thermally induced polymerization yields linear crown ether fluoropolymers with hexafluorocyclobutyl linkages. The polymers exhibit T~g~'s above 120โ€‰ยฐC and show good thermal stability with no appreciable weight loss below 350โ€‰ยฐC. Incorporation of crown ether macrocycles into the polymer is expected to increase cationic uptake of an otherwise electroneutral fluoropolymer.

Liquid crystalline polyetheresters with crown ethers in the mesogenic unit have been synthesized using the DB-[ 181-C-6 crown. This compound was then transferred to the diacetyl-, dicarboxy-and dicarboxydichloride derivatives. After incorporation of the crown ether moiety into the mesogens of main c
