Original Abstract Submitted
Provided is a perfluoropolyether-organopolysiloxane block copolymer that has a perfluoropolyether group, that allows control of, for example, the number of siloxane units in the molecule, and that has excellent affinity with non-fluorinated organic compounds. A perfluoropolyether-organopolysiloxane block copolymer of the present invention is a perfluoropolyether-organopolysiloxane block copolymer having a perfluoropolyether block and an organopolysiloxane block. The organopolysiloxane block has, as a side chain thereof, one or more groups selected from an aralkyl group and a group having an oxyalkylene unit.
