1. A manufacturing method for obtaining an organopolysiloxane-polyoxyalkylene block copolymer, said method comprising reacting: (A) a polyoxyalkylene compound represented by formula (1) below: wherein: Rl are each independently a substituted or unsubstituted, straight, branched, or cyclic monovalent hydrocarbon group having from 1 to 30 carbons and that is free of unsaturated aliphatic bonds; or an alkoxy group having from 1 to 30 carbons; R2 are each independently R1 or X1; X1 are each independently a reactive functional group represented by —R3—Z1 (where R3 is directly bonded or is a substituted or unsubstituted, straight or branched divalent hydrocarbon group having from 1 to 20 carbons; and Z1 is an amino group-containing group or an ammonium group-containing group); D are each independently a group selected from group represented by the formula below: (wherein R4 is an oxygen atom, a sulfur atom, or —N(R6)— (wherein R6 is a hydrogen atom or a substituted or unsubstituted, straight, branched, or cyclic monovalent hydrocarbon group having from 1 to 30 carbons); a substituted or unsubstituted, straight or branched divalent hydrocarbon group having from 1 to 20 carbons; or a substituted or unsubstituted, straight or branched divalent hydrocarbon group comprising at least one hetero-atom and having from 1 to 20 carbons) and —N(R5)2 (where R5 is a hydrogen atom or a substituted or unsubstituted straight, branched, or cyclic monovalent hydrocarbon group having from 1 to 30 carbons); Y are each independently a substituted or unsubstituted, straight or branched divalent organic group having from 1 to 20 carbons; c is a number not less than 2; d is a number not less than 0; and m are each independently a number not less than 0, n are each independently a number not less than 1, and m+n is a number in a range from 1 to 10,000; and (B) a polyorganosiloxane represented by the following formula (2): wherein: R′, X′, and R2 are synonymous with those described above (however, only when E is a hydrogen atom, R1 may be a hydroxyl group); E is a hydrogen atom; and p is a number not less than 1, q is a number not less than 0, and p+q is a number in a range from 1 to 10,000; wherein the organopolysiloxane-polyoxyalkylene block copolymer includes a unit represented by the following formula (3): wherein R1, R2, X1, Y, c, and d are synonymous with those described above; a is a number not less than 1, b is a number not less than 0, and a+b is a number in a range from 1 to 10,000; and e is a number not less than 1. |
