  • Composition containing liquid crystalline polymer
    Patent number: 6126856
    Abstract: When small amounts of zeolite or titanosilicates are added to thermotropic liquid crystalline aromatic polyester, poly(ester-amide) or poly(ester-imide) compositions, the compositions become less flammable. In many cases addition of the zeolite or titanosilicates does not significantly affect other properties of the composition, which may be used as molding resins, for instance to make parts useful in the electrical, electronic or automotive industry.
