A pelletizer for liquid polymers in which the severed pellets fall from cutter knives into an annulus on the surface of a body of cooling liquid. The annulus is defined by said surface and the confluence of a downwardly flowing ring of the cooling liquid and a downwardly and radially outwardly flowing cascade of the cooling liquid. The velocity and trajectory of the pellets are controlled by the projection of a spray of cooling liquid radially across the dies from which the pellets are severed. Band heaters in proximity to the dies maintain the polymer in a liquid state prior to extrusion.
