Liquid catalyst composition is fed to a fluidized bed olefin polymerization reactor through an ultrasonic nozzle, enabling improved control over average catalyst composition droplet size and size distribution, which provides better control over resin particle size. The spray may be surrounded by a shroud of gas which creates a particle lean zone, thus reducing the likelihood of contact by the catalyst composition with existing product particles already suspended in the fluid bed.
