1. method for preparing siloxanes liquid crystal or vesica, this method comprises:

  • In the presence of platinum catalyst, make (A) (i) general formula be R 3SiO (R '"'"' 2SiO) a(R " HSiO) bSiR 3, (ii) general formula HR 2SiO (R '"'"' 2SiO) cSiR 2H or (iii) general formula be HR 2SiO (R '"'"' 2SiO) a(R " HSiO) bSiR 2(wherein in these general formulas, R, R '"'"' and R " are the alkyl with 1-6 carbon atom to the polysiloxane that contains ≡

    Si-H of H;

    A is 0-250;

    B is 1-50;

    With c be 0-250) and (B) general formula be CH 2=CH (CH 2) xO (CH 2CH 20) y[CH 2CH (CH 3) O] zThe mono-alkenyl polyether of R (wherein R represents hydrogen or contains the alkyl of 1-10 carbon atom, and x is 1-6, and y is 0 or numerical value 4-100, and z is 0 or numerical value 4-100, and condition is that y or z are not 0 simultaneously) reaction, the polysiloxane that contains ≡

    Si-H that has polyether-based up to formation;

    Then In the presence of platinum catalyst, make (C) described polysiloxane that contains ≡

    Si-H with polyether-based, (D) being selected from general formula is CH 2=CH (CH 2) xCH=CH 2The α

    of (wherein x is 1-20), ω

    -diolefine, general formula are CH ≡

    C (CH 2) xThe α

    of C ≡

    CH (wherein x is 1-20), ω

    -diyne and general formula are CH 2=CH (CH 2) xThe α

    of C ≡

    CH (wherein x is 1-20), unsaturated hydrocarbons in ω

    -alkene-alkynes and (E) water reaction are up to forming siloxanes liquid crystal or vesica.
