METHOD FOR PRODUCING OLEFIN POLYMER COMPOSITION INCLUDING STRUCTURAL UNIT DERIVED FROM ORGANIC ACID COMPOUND

Japanese Patent JP2022110432

A

SOLUTION: To provide a method for producing an olefin polymer composition which brings an olefin polymer (A), an organic acid compound (B) and a radical initiator (C) into contact with each other in a reactor in a flow condition under the following conditions (X1) to (X3): (X1) condition of Expression (1): 0.01<(Aw(2/3)/(Bw×VA(1/4)))<100 is satisfied, wherein Aw represents a product (g/cm2 hour) of a percentage content (g/cm3) per volume of the olefin polymer (A) in the flow condition and flow linear velocity (cm/hour) of (A), Bw represents single speed (g/cm2 hour) of (B), and Va is a volume of liquid containing (A) (m3); (X2) temperatures (T)(°C) of (A), (B) and (C) and a 1.5 hr half-life temperature (T1)(°C) of (C) satisfy Expression (2): T1
