WIPO Patent Application WO/2024/080124

A1

This method for producing a composition, which includes an olefin-based polymer A and a polyhydroxyalkanoate-based polymer B, and which contains 99.9-70 parts by mass of the olefin-based polymer A and 0.1-30 parts by mass of the polyhydroxyalkanoate-based polymer B with respect to the total 100 parts by mass of the olefin-based polymer A and the polyhydroxyalkanoate-based polymer B, comprises the steps of: supplying, to an extruder, a material 1 containing the olefin-based polymer A from a main feed port of the extruder and melting and kneading the material 1; and supplying, to the extruder, a material 2 containing the polyhydroxyalkanoate-based polymer B from a side feed port arranged on the downstream side of the main feed port in the extruder, and melting and kneading the material 2.
