AQUEOUS DISPERSION OF PARTICLES OF AT LEAST ONE THERMOPLASTIC POLYMER, METHOD FOR PREPARING AND APPLICATIONS THEREOF, ESPECIALLY FOR SIZING REINFORCING FIBRES

The invention relates to the use of giant micelles as shear-thinning agent in an aqueous dispersion of particles of at least one thermoplastic polymer. It also relates to an aqueous dispersion of particles of at least one thermoplastic polymer, comprising giant micelles located around the particles of the thermoplastic polymer(s), and also to a method that makes it possible to prepare this aqueous dispersion. Applications: all fields in which it is desirable to coat a substrate with a thermoplastic film and, in particular, the sizing of reinforcing fibres intended to be incorporated into the composition of parts made of thermoplastic matrix composite materials and, in particular, of structural parts for the aeronautical and space industries.
