Document Type and Number:
Japanese Patent JP2023177838
Kind Code:
A
Abstract:
To provide a propylene block copolymer that can yield a molding with superior surface properties such as fouling prevention and low friction, and a polymer composition including the same and a molding thereof.SOLUTION: A propylene block copolymer includes a structural unit wherein a block predominantly composed of a propylene unit and a block predominantly composed of a siloxane unit form Si-C bonds. For example, the number of siloxane units is 50 or more and 300 or less for every 1000 propylene units.SELECTED DRAWING: None
