发明名称 Resin Composition for Extrusion Molding and Extrusion-Molded Article
摘要 A purpose of the present invention is to obtain a hollow extruded article by easy blow molding or extrusion molding to give a draw down resistance and a uniform wall thickness of the article without damaging low gas permeability which is a characteristic property of a liquid-crystalline polymer. A resin composition for extrusion molding which is prepared by melting and kneading 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 Temperature T1 which is higher than 20° C. from said melting point, and containing (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; and 1-30 wt. % of epoxy modified polyolefin type resin (B), and has a melt viscosity at 1000/sec. shear rate of 60-4000 Pa.s at said Temperature T1, and a melt tensile strength of 20 mN or more at 14.8 m/min. draw rate is used.
