    Abstract: An alignment layer for a liquid crystal display device is described. The alignment layer comprises a copolymer of a thermoset polymer containing perfluorinated cyclobutane rings and a thermoplastic polymer containing perfluorinated cyclobutane rings, or a blend of thermoset and thermoplastic homopolymers or copolymers containing perfluorinated cyclobutane rings. This copolymer or blend provides an alignment layer with a cure temperature of less than 250 DEG C, a low dielectric, and a low moisture content. The resultant alignment layer can also provide surface tilt angles suitable for supertwisted nematic-liquid crystal displays.

    Abstract: The present invention is directed to a compound and a process for preparing a compound having at least one perfluorovinyl group and at least one functional group, the compound suitable for reacting with and/or forming polymers. The compound is preferably represented by the following formula (I): (G)n-R-(X-CF=CF2)m, wherein R represents an optionally substituted hydrocarbyl group, X represents any group which links R and a perfluorovinyl group; n is an integer of at least 1, m is an integer of at least 1; and G represents any reactive functional group or a group convertible into a reactive functional group. The process for preparing the compound of formula (I) comprises the steps of: (a) preparing a 2-halotetrafluoro compound of the following formula (III): (Q-CF2-CF2-X)m-R-(G'')n, wherein R, X, m and n are as defined for formula (I) and Q is bromine, chlorine or iodine; and G'' is a functional group G, or a functional group suitable for conversion into G; (b) chemically modifying group G'' to produce functional group G where G'' is a functional group suitable for a conversion into G; and (c) dehalogenating the 2-halotetrafluoro compound to form the corresponding trifluorovinyl compound.

    Abstract: The present invention includes a process for preparing a polymer having perfluorocyclobutane rings by the steps of (a) contacting monomers having at least two dimerizable perfluorovinyl groups; and (b) exposing the monomers to heat such time that a polymer containing perfluorocyclobutane rings is formed. The present invention includes polymers having a backbone comprising hydrocarbyl groups, perfluorocyclobutane rings and non-carbon atoms and polymers of at least 10,000 molecular weight having repeating units [O-(CFRf)n-O-perfluorocyclobutane]. The present invention also includes crosslinked polymers having perfluorocyclobutane rings and thermal processes to prepare such crosslinked polymers. Crosslinked polymers have tensile strength and other physical properties enhanced over the properties of the corresponding linear polymer.
