18 Claims

1. A method for drying a wet polymer composition obtained from a polymerization process, comprising:

a) introducing the wet polymer composition and a drying gas into a fluidized bed dryer to form a fluidized bed of the wet polymer composition and

b) heating the fluidized bed to obtain a dry polymer composition,

wherein the fluidized bed further comprises an anti-fouling agent comprising inert nanoparticles,

wherein the wet polymer composition comprises powders of one or more polymers selected from the group consisting of polyolefins.
