Abstract: Methods and systems for pelletizing high melt flow polystyrene are described herein. The method generally includes providing a polystyrene including a melt flow index of about 16 g/10 min to about 34 g/10 min; extruding a strand of the polystyrene through a die head, wherein a temperature of the polystyrene at the die head is from about 370° to about 430° F.; and moving the strand through a bath, wherein a temperature of the bath is from about 95° to about 145° F.
