Abstract
Abstract A surface modifier comprising a block copolymer obtained by polymerizing a polyfluoroalkyl group-containing compound in the presence of a chain transfer agent composed of a polysiloxane having a mercapto group at its terminal, said block copolymer containing polymer segments of said polysiloxane and polymer segments of said compound, as essential components.
