Abstract
The present invention provides a liquid crystalline resin composition capable of readily blow-molding a molded article having uniform thickness, with the addition of good blow-moldability owing to the improved drawdown-resistant property, the improved melt-tension increase rate, and other properties without deteriorating the low gas-permeability which is a characteristic of liquid crystalline resin. Specifically, it provides a liquid crystalline resin composition for blow molding, obtainable by melt-kneading: (A) 100 parts by weight of a melt-processable aromatic polyester and/or polyester amide, which can form an anisotropic molten phase; (B) 10 to 25 parts by weight of a styrene-based copolymer composed of 40 to 97% by weight of a styrene group, 60 to 3% by weight of a specific glycidyl ester of α,β-unsaturated acid and 0 to 50% by weight of other vinyl-based monomer, wherein the styrene-based copolymer has epoxy equivalents ranging from 300 to 3000 g/eq, and weight average molecular weights of 30000 or more; and (C) 0 to 100 parts by weight of one or more of fibrous filler, powdery or granular filler, and plate-like filler.
