Abstract
The present invention deals with a process for producing pellets from olefin copolymers. The process comprises: (i) melting the olefin copolymer in an extruder; (ii) extruding the molten olefin copolymer through a die plate into a pellet water bath in a pelletizer thereby producing strands of the olefin copolymer; (iii) cutting the strands of the olefin copolymer in the pelletizer into pellets; and (iv) drying the pellets. The pellet water in the pelletizer contains from 0.1 to 5% by weight of a colloidal silica based on the weight of the water.
