Pseudolatex preparation by direct displacement of partially water-miscible solvents from a conventional emulsion

摘要

Pseudolatexes (PL) are typically prepared by the emulsification-evaporation technique patented by Vanderhoff (1): a polymer solution in a water-immiscible organic solvent is emulsified in an aqueous phase containing emulsifiers. This crude emulsion is then submitted to a high energy source, e. g., ultrasound radiation, or is passed through homogenizers, high pressure dispersers, colloid mills, etc.
