Patent ID: 7737198

Claim:
A molded product comprising a dielectric constant of 3.0 or less and a dielectric dissipation factor of 0.04 or less obtained by the injection molding of a wholly aromatic liquid crystal polyester resin composition which comprises 45 to 90 percent by weight of a wholly aromatic liquid crystal polyester having a melting point of 320° C. or more, 10 to 40 percent by weight of an inorganic spherical hollow material having an aspect ratio of 2 or less, and 0 to 15 percent by weight (100 percent by weight as a total) of an inorganic filler having an aspect ratio of 4 or more, and wherein the apparent viscosity of the liquid crystal polyester at a temperature of 20° C. above the melting point of the liquid crystal polyester is 5,000 poise or less, and wherein the fracture rate X of the inorganic spherical hollow material is 0.045 to 0.094 using the following equation: ρ=100/[α/ρ1+β/ρ2+γ(1 −X )/ρ3 +γX /ρ4], where in the equation: α=the percent by weight of the wholly aromatic liquid crystal polyester resin; β=the percent by weight of the inorganic filler having an aspect ratio of 4 or more; γ=the percent by weight of the inorganic spherical hollow material having an aspect ratio of 2 or less; ρ=the specific gravity of the wholly aromatic liquid crystal polyester resin composition; ρ1=the specific gravity of the wholly aromatic liquid crystal polyester resin; ρ2=the specific gravity of the inorganic filler having an aspect ratio of 4 or more; ρ3=the true specific gravity of the inorganic spherical hollow material having an aspect ratio of 2 or less; ρ4=the material specific gravity of the inorganic spherical hollow material; X=the fracture rate of the inorganic spherical hollow material; γ(1−X)=the percent by weight of non-fractured inorganic spherical hollow material; γX=the percent by weight of fractured inorganic spherical hollow material.
