  • High strength thermotropic liquid crystalline polymer
    Patent number: 9206300
    Abstract: A wholly aromatic thermotropic liquid crystalline polymer and compositions including the liquid crystalline polymer are described. The polymer composition can include the liquid crystalline polymer and a fibrous filler, e.g., a chopped glass or milled glass fibrous filler. The compositions are capable of exhibiting excellent mechanical properties. The liquid crystalline polymer provides desirable characteristics with the incorporation of little or no naphthenic acids in the polymer backbone.
