Patent ID: 8053521

Claim:
A polishing pad, comprising 60 to 99 parts by weight of a polymer matrix (A) comprising 1,2-polybutadiene; and 1 to 40 parts by weight of component (B) comprising a copolymer having a polyether block, wherein the total amount of the polishing pad is 100 parts by weight, polymer matrix (A) comprises 1,2-polybutadiene in an amount of at least 60 parts by weight, relative to 100 parts by weight of the polishing pad, component (B) comprises the copolymer having a polyether block in an amount of at most 40 parts by weight relative to 100 parts by weight of the polishing pad, and the polishing pad has a surface resistivity of from 2.6×10 7 to 9.9×10 13 Ω.
