Abstract
The present invention relates to copolyethers constituted by copolymers of 7,oxa-bicyclo(2,2,1)heptane, and its alkyl-derivatives, with one or more cycloaliphatic ethers, comprising from 2 to 4 carbon atoms in their ring. These copolyethers show an anisotropic behavior in the molten state, and therefore are endowed with liquid-crystal properties.
