Fluorine-containing acrylate and methacrylate side-chain liquid crystal monomers and polymers

摘要

The present invention relates to novel fluorinated acrylate and methacrylate ester monomers and homopolymers and copolymers thereof. In another aspect, it relates to a process for preparing monomers of the invention. Homopolymers and copolymers of the invention have units which correspond to the following general chemical formula: ##STR1## wherein R is hydrogen, halo, a C.sub.1 to C.sub.4 alkyl or haloalkyl group, or a C. sub.6 to C.sub.10 aryl group,PPW is --O-- or --NR.sup.1 -- , wherein R.sup.1 is hydrogen or a C.sub.1 to C.sub.4 alkyl group, PPX is a carbon-to-carbon single bond or a spacer group, PPY is a mesogenic group, andPPZ is a fluorinated alkyl group.PPThe novel monomers and polymers can be liquid crystals.
