  • Process for blow molding articles from liquid crystal polymers
    Patent number: 5443783
    Abstract: Disclosed is a process for blow molding articles from liquid crystal polymers containing ionic moieties in the backbone. The ionic moieties increase the melt viscosity of the polymers sufficiently high to blow mold articles therefrom. An illustrative liquid crystal polymer is made from 4-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid and sodium 5-sulfoisophthalate.
    Type: Grant
    Filed: March 23, 1993
    Date of Patent: August 22, 1995

  • Laminates of wholly aromatic liquid crystalline polymers containing ionic monomer units
    Patent number: 5292589
    Abstract: A melt processable wholly aromatic liquid crystalline polymer capable of forming an anisotropic melt phase at a temperature below approximately 400.degree. C. having enhanced adhesion properties containing from approximately 0.05 to approximately 2.0 mole percent of a recurring sulfonated, ionic moiety in the backbone of the polymer. The polymer is useful for the production of laminate structures.

  • Thermoset resin produced from anisotropic heat-curable acrylic-terminated monomers
    Patent number: 4514553
    Abstract: Novel heat-curable acrylic-terminated monomers are provided which exhibit an optically anisotropic melt phase at a temperature which enables it to undergo melt processing in the formation of molded articles, etc. The monomers are capable of being heat-cured at temperatures in excess of the melt processing temperatures to produce a thermoset self-reinforced composite. The monomer may, for example, consist essentially of the reaction product of p-acryloyloxybenzoic acid and a difunctional aromatic moiety in a molar ratio of about 2:1.
