Abstract

PURPOSE:To obtain a polyester made, preliminary molded product with a bottom which provides a blow-molded container that is made of polyethylene tere-phthalate resin added with a given compound, and that has a drum portion of a given crystallinity, an excellent strength and heatproof contractivity, and an improved slipping property. CONSTITUTION:Polyethylene terephthalate resin added with 0.002-0.5wt% of at least one type of compound selected from a group, which consists of kaolin, white carbon, talc, sodium benzonate, sodium stearate, barium stearate, aintimony trioxide, titanium oxide, and silicon oxide, is dried until moisture content thereof becomes 0.01% or less. The resin is then molded into a desired preliminary molded product with a bottom by an ordinary injection-molding or extrusion-molding method, and thereby a desired preliminary molded product with a bottom for blow- molded container made of polyester, in which a crystallinity of a drum portion thereof is 1.0-10.0%, can be obtained.
