摘要： The invention relates to a method for extracting high-quality polyisoprene by grinding plants via rotary shearing using a device comprising at least one rotor and at least one stator, into particles of size smaller than 1 mm, or grinding at a pH higher than 3 and lower than 8. This method is implemented in aqueous phase and allows the preparation of a dispersion of polyisoprene in water having a weight average molecular weight (MW) higher than 800 000 g/mol. The polyisoprene is extracted from plants and in particular from guayule (Parthenium argentatum). It is a method that is particularly heedful of the environment.
