Abstract

A process for producing polymer particles by polymerizing liquid droplets in a gas phase by metering a liquid comprising at least one monomer from at least one feed by means of a multitude of bores into a reaction chamber comprising the gas phase, wherein ratio of length of the feed to greatest diameter of the feed in the region of the multitude of bores is at least 10.
