| abstract |
The invention relates to a polyether/aminopolysiloxane block copolymer and use thereof. The polyether/aminopolysiloxane block copolymer is prepared mainly by reacting a compound shown in a formula I with a compound shown in a formula II at 50 to 90 DEG C, and has the viscosity of 2,000 mPa.S to 7,500 mPa.S at 25 DEG C. The block copolymer can be used as a textile softening finishing agent. In theformulae I and II, R1 is H, C1 to C6 are linear or branched chain alkyls or hydroxyls, a is an integer from 0 to 20, m is 4 to 13, and n is 12 to 25. |
