[0036]
[0037] 100 parts by weight of 1-butene monopolymer (manufactured by Mitsui Chemicals, Inc., P5050) and 40 parts by weight of acetylene black (manufactured by Denki Kagaku Kogyo Co., Ltd., DENKA BLACK powder, DENKABLACK HS-100 or DENKA BLACK FX-35), A twin-screw extruder was used to melt and knead at a molding temperature of 200° C. to prepare a high-concentration masterbatch in which the content of acetylene black relative to the 1-butene monomer was 40% by weight.
[0038] The obtained masterbatch and the above-mentioned 1-butene monomer are melted and kneaded with a single-screw extruder at a molding temperature of 200° C. to obtain a content of 0.1% by weight of acetylene black relative to the 1-butene monomer. or 2.0% by weight of a 1-butene monomer composition.
