| titleOfInvention | Method for Producing Olefin Polymer Mixture |
| abstract | PROBLEM TO BE SOLVED: To mix a crystalline polyolefin having a specific composition and an ethylene-based copolymer with a powdery or granular additive in a mixer having a mixing tank and a stirring blade for mixing. Provided is a method for producing a mixture in which additives are less likely to remain in the mixing tank. (A) 65 to 45 parts by mass of pellets of a copolymer containing a structural unit derived from ethylene and a structural unit derived from an α-olefin having 3 to 20 carbon atoms. (B) 35 to 55 parts by mass of pellets of crystalline α-olefin polymer having a melting point of 135 to 170 ° C. measured by DSC (however, the total of components (A) and (B) is 100 parts by mass). , And (C) powdery or granular additives containing at least a component having a melting point of 30 to 150 ° C. measured by DSC, 0.001 to 3 based on a total of 100 parts by mass of the components (A) and (B). Mass part, Mixing is carried out in a mixer having a mixing tank and a stirring blade for mixing under the conditions of a peripheral speed of the stirring blade of 1 to 50 m / s and a product of the depth of the mixing tank and the peripheral speed of the stirring blade of 15 to 100 m 2 / s. A method for producing an olefin-based polymer mixture, and a method for producing an olefin-based polymer composition, which comprises melt-kneading the mixture obtained by the above-mentioned production method.
