PROBLEM TO BE SOLVED: To obtain a product, which is a blown molding excellent in surface properties and, at the same time, the blow molding workability and impact resistance of which balance is well with each other by a method wherein the surface gloss of the blown molding is set to be a predetermined value and its reflectance is set to be below a predetermined value. SOLUTION: The surface gloss of a blown molding is 5% or less at 60 deg. reflectance. The blown molding is obtained by mixing a graft copolymer A and a vinyl-based copolymer B together. The graft copolymer A is produced by reacting 0.1-40 wt.%, more preferably 0.5-30 wt.% of anα,β-unsaturated acid glycidyl ester compound as an essential component, 10-40 wt.% of cyanide vinyl compound, 60-90 wt.% of aromatic vinyl compound and 0-30 wt.% of other copolymerizable vinyl compound together. The vinyl-based copolymer B is produced by reacting 10-40 wt.% of a cyanide vinyl compound, 60-90 wt.% of an aromatic vinyl compound and 0-30 wt.% of other copolymerizable vinyl compound together. |
