MULTILOBED POLYESTER PELLETS

Polyester multilobed prepolymer pellets and methods of making and using the same are provided. The multilobed polyester pellets have an increased surface area to volume ratio which improves intraparticle diffusion mass transfer rates resulting in a reduction of pellet drying and solid state polymeri...
