1. , for a continuous monomer emulsions preparation method for polymerization technique, described method comprises:

  • By managing (110) supply first liquid in pipe-in-pipe injector, wherein said interior pipe (110) has the port of export (118), and the described port of export (118) is positioned at the front surface of the rotor of Rotor-stator mixers (102) (104) (122) at a distance of preset distance (120) place;

    Second liquid is supplied to described Rotor-stator mixers (102) by the outer tube (108) of described pipe-in-pipe injector, the density of wherein said second liquid is less than the density of described first liquid, and at least one in wherein said first liquid and described second liquid contains monomer, and described first liquid from by from described outer tube (108) described second liquid around in pipe (110) discharge, and to flow with the common direction (134) of the described second liquid from described outer tube (108) is upper;

    WithEmulsion is formed continuously by described first liquid and described second liquid in described Rotor-stator mixers (102),Wherein said method also comprises start-up technique, wherein before the described second liquid of supply, supplies first liquid to fill described Rotor-stator mixers,Wherein, once described first liquid is filled with Rotor-stator mixers and obtains liquid counterpressure, just described second liquid is fed to described Rotor-stator mixers with the second mass flow lower than its final mass flow,Wherein, the initial mass flow of described second liquid is 50% of the final mass flow of described second liquid,Wherein, within the predetermined time described second mass flow is increased to the final mass flow of described second liquid, andWherein, described interior pipe (110) has internal diameter (125), and with 1.5 to 0.5 times of described front surface (122) the described preset distance (120) apart of described rotor (104) internal diameter (125) that is described interior pipe (110).
