Title:
POLYBUTADIENE MIXTURE AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2020132825
Kind Code:
A
Abstract:
To provide: a polybutadiene mixture that makes it possible to obtain a polybutadiene resin excellent in tensile strength, extension and toughness; and a method for manufacturing the polybutadiene mixture.SOLUTION: A polybutadiene mixture is manufactured with a method including the step Y of polymerizing 1,3-butadiene in the presence of 1,2-polybutadiene and a lanthanoid catalyst. A mass ratio of 1,2-polybutadiene and 1,3-butadiene is 1,2-polybutadiene/1,3-butadiene=95/5 to 50/50.SELECTED DRAWING: None
