Abstract:
1. A resin composition for extrusion molding, prepared by mixing 99-70 wt. % of wholly aromatic polyester amide liquid crystal resin (A) having a melting point of 270-370° C. and a melt viscosity at 1000/sec. shear rate of 20-60 Pa·s at a temperature (as referred to Temperature T1) higher than 20° C. from said melting point, and comprising (I) to (V) repeating polymeric units as follows: (I) 1-15 mole % of 6-hydroxy-2-naphthoic acid residue, (II) 40-70 mole % of 4-hydroxybenzoic acid residue, (III) 5-28.5 mole % of aromatic diol residue, (IV) 1-20 mole % of 4-aminophenol residue, and (V) 6-29.5 mole % of aromatic dicarboxylic acid residue (wherein the aromatic diol residue and the aromatic dicarboxylic acid residue are divalent groups containing at least one aromatic ring); and 1-30 wt. % of epoxy modified polyolefin type resin (B) (the total of both is 100 wt. %), followed by melting and kneading thereof, wherein a melt viscosity at 1000/sec. shear rate of said resin composition at said Temperature T1 is 60-4000 Pa·s, and a melt tensile strength at 14.8 m/min. draw rate is 20 mN or more.
