Fluorine-containing, chiral liquid crystal compounds comprise (a) a chiral fluorochemical terminal portion containing at least one methylene group and optionally containing at least one catenary ether oxygen atom; (b) a saturated, chiral or achiral, hydrocarbon terminal portion; and (c) a central core connecting the terminal portions. The compounds have smectic mesophases or latent smectic mesophases and are useful, for example, in liquid crystal display devices.

Liquid crystal compounds having a chiral fluorinated terminal portion

Fluorine-containing liquid crystal compounds comprise a fluorocarbon terminal portion having at least one catenary ether oxygen and a hydrocarbon terminal portion, the terminal portions being connected by a central core. The compounds have smectic or latent smectic mesophases.

Liquid crystal compounds having perfluoroether terminal portions

Fluorine-containing, chiral liquid crystal compounds comprise (a) an aliphatic fluorocarbon terminal portion containing at least two catenary ether oxygen atoms; (b) a chiral, aliphatic hydrocarbon terminal portion; and (c) a central core connecting the terminal portions. The compounds have smectic mesophases or latent smectic mesophases and are useful, for example, in liquid crystal display devices.

Chiral liquid crystal compounds having a perfluoroether terminal portion

Fluorine-containing liquid crystal compounds are provided. The compounds comprise a fluorocarbon terminal portion having at least one catenary ether oxygen and a hydrocarbon terminal portion, the terminal portion being connected by a central core, the compounds having smectic mesophases or having latent smectic mesophases.

Fluorine-containing, chiral and achiral liquid crystal compounds comprise (a) an aliphatic fluorocarbon terminal portion comprising a perfluorinated or partially-fluorinated alkylene group and a terminal hydrocarbon alkyl group, the groups optionally containing at least one catenary ether oxygen atom; (b) an aliphatic hydrocarbon terminal portion; and (c) a central core connecting the terminal portions. The compounds have smectic mesophases or latent smectic mesophases and are useful, for example, in liquid crystal display devices.

Organic solvent soluble, acryloyloxy and methacryloyloxy group-containing, condensation polymers are crosslinkable and useful for providing chemical, solvent, and abrasion resistant articles. The condensation polymers are polyesters or polyurethanes having an acryloyloxy or methacryloyloxyalkanediol component that is uncontaminated by hydroxyl group-containing compounds having one, three, or more hydroxyl groups or compounds in which the acryloyloxy or methacryloyloxy group is attached to a secondary carbon atom.

Acryloyloxy and methacryloyloxy group-containing condensation polymers

Organic solvent soluble, acryloyloxy and methacryloyloxy group-containing, condensation polymers are crosslinkable and useful for providing chemical, solvent, sand abrasion resistant articles. The condensation polymers are polyesters or polyurethanes having an acryloyloxy or methacryloyloxyalkanediol component that is uncontaminated by hydroxyl group-containing compounds having one, three, or more hydroxyl groups or compounds in which the acryloyloxy or methacryloyloxy group is attached to a secondary carbon atom.

A coating composition is provided. The coating composition is a curable blend of ethylenically unsaturated polyester and ethylenically unsaturated thermoplastic polymers. The composition is capable of providing a thermoplastic, soluble, sandable, intermediate-stage coating and, when cured, a final stage coating which is unaffected by acetone placed on the final stage coating for two hours at 22.degree. C., has a percent haze value of 15% or less, and is unaffected when subjected to a Wet Print Test.

Radiation-curable thermoplastic coating

Ethylenically unsaturated polyesters are provided. These ethylenically unsaturated polyesters are the reaction product of (a) a polyhydroxy polyester material that is the reaction product of at least one organic dicarboxylic acid, at least one diepoxide, and, optionally, monocarboxylic acid and/or monoepoxide with (b) a polymerizable ethylenically unsaturated compound having a functional group reactive with the hydroxyl groups of the polyhydroxy polyester. This product is particularly useful as a protective coating material.
