PROBLEM TO BE SOLVED: To obtain blow moldings having good appearance characteristics and uniformity by using resin compositions excellent in gas-assist injection molding properties. SOLUTION: With the use of resin compositions comprising, based on (A) 100 pts.wt. polybutylene terephthalate resin(PBT resin), (B) 5-100 pts.wt. at least one resin selected from a polycarbonate resin and a polyethylene terephthalate resin(PET resin), blow moldings 6 are obtained by gas-assist injection molding. The PBT resin and PET resin may be copolymer resins having 5-40 mole% comonomer units, respectively. The resin compositions may contain 0.01-5 pts.wt., based on 100 pts.wt. PBT resin, phosphorus-based compound (C). |
