  • Publication number: 20030212204
    Abstract: Polyarylenesulfide resin compositions are provided having a dramatically improved adhesiveness with regard to the cured epoxy resin, while maintaining characteristics of polyarylenesulfide resins such as a heat resistivity and a chemical resistivity. The above described polyarylenesulfide resin compositions are obtained by comprising as essential components the allylenesulfide resin (A), bisphenol-type epoxy resin (B), and an oxazoline-group-containing amorphous polymer (C). The thus obtained polyarylenesulfide resin compositions can be used as superior engineering plastics in wide application fields such as electronic and other devices.

  • Publication number: 20020034709
    Abstract: The present invention provides a photo-alignment layer for a liquid crystal display device, which has good liquid crystal display device characteristics such as a good voltage holding ratio and also has good alignment stability and sufficient resistance to light and heat. The photo-alignment layer is manufactured by coating a polymerizable monomer having at least one photo-alignment moiety, which carries out a photo-alignment function by the photo dimerization reaction, and at least two polymerizable maleimide groups per molecule on a substrate, and exposing the coating layer to light to cause the photo dimerization reaction of the structural unit and the photopolymerization reaction of the polymerizable maleimide group, thereby to form a crosslinked polymeric layer and to enable the polymeric layer to carry out the photo-alignment function.
