Abstract: 　Polysiloxane, as an organic silicon polymer， can be chemically modified by block copolymerization. Because of its abundant raw materials and excellent properties of modified products, it has been extensively studied by scholars. In this paper, the research progress of polysiloxane block copolymers at home and abroad was reviewed. Some kind of polysiloxane block copolymers modified by polyurea, polyurethane, polyether, polyamide and polyimide were mainly introduced. Also, its performance and application were summarized, and the prospect of its application was forecasted.

Key words: Polysiloxane, Block copolymers, Polyurea, Polyurethane, Polyester, Polyamide, Polyimide
