PURPOSE:To remarkably reduce drawdown and facilitate the blow molding of a large part by compounding at least one resin selected from the group consisting of a polycarbonate resin and a polybutylene terephthalate resin, a specific high-molecular weight acrylic copolymer, and carbon black. CONSTITUTION:100 pts.wt. at least one resin selected from the group consisting of a polycarbonate resin (derived from a dihydric phenol and having a viscosity average mol.wt. of 10000-100000, pref. 15000-60000) and a polybutylene terephthalate resin (pref. having an intrinsic viscosity in o-chlorophenol at 25 deg.C of 0.8-2.0), 0.1-8 pts.wt. acrylic copolymer [contg. at least 30wt.% alkyl methacrylate and at lest 5wt.% alkyl acrylate and having a relative viscosity (0.1g polymer/10dl methylene chloride) of 0.2 or higher], and 0.5-6 pts.wt. carbon black (having a specific surface area of 150m<2>/g or higher and an oil absorption of 500ml/100g or higher) are compounded to give a thermoplastic resin compsn. suitable for blow molding. |
