<p>The present invention is to provide a process for producing a molded product by blow molding a mixture containing a polyolefin resin and a polyethylene wax which having a density of 890 to 980 (kg/m 3 ) as determined by the density gradient tube method in accordance with JIS K7112 and a number average molecular weight (Mn) of 500 to 3,000 in terms of polyethylene as determined by gel permeation chromatography (GPC) and satisfying the relationship represented by the following expression (I): B ‰¤ 0.0075 × K (In the above formula (I), B is a content ratio (% by weight) of components having a molecular weight of 20, 000 or more in terms of polyethylene in the polyethylene wax as determined by gel permeation chromatography and K is a melt viscosity (mPa·s) of the polyethylene wax at 140°C.)
According to the present invention, in producing a molded product by blow molding using a polyolefin resin as a raw material, the productivity at the time of the blow molding is improved, and a molded product which is not impaired in the mechanical properties inherent in a polyolefin resin is provided.</p> |
