  • Mixtures of liquid crystalline copolymers and fluorothermoplastics, and use thereof
    Patent number: 5466738
    Abstract: Mixtures of liquid crystalline copolymers and fluorothermoplastics, and use thereof.Mixtures of A) liquid crystalline copolymers and B) fluorothermoplastics, having a proportion of A) of 45 to 97% by weight and a proportion of B) of 3 to 55% by weight, have an improved notched impact strength. They are therefore particularly suitable for producing molded articles or as a matrix material for composites.
