1. A method for treating polymer particles, the method including providing polymer particles and providing a carrier liquid, the method further including the steps:

(a) mixing said polymer particles with said carrier liquid to form a dispersion of said particles in said carrier liquid at a concentration of at least 0.1 g/L, based on the volume of the dispersion; and

(b) subjecting the dispersion to microfluidization treatment thereby causing particle stretching, particle size reduction and increasing the surface area per unit mass of the polymer particles.
