The invention relates to a process and an apparatus for pelletizing polymer melts comprising blowing agent in a pelletizing chamber through which a liquid flows, its pressure being above the ambient pressure. In a first step, the polymer melt is injected into the pelletizing chamber, in a second step the polymer melt is cut via a cutting apparatus into individual pellets and, in a third step, the pellets produced in the pelletizing process are discharged with the liquid from the pelletizing chamber and are then isolated from the liquid. This process also comprises at least one of the following steps:

Method and device for granulating polymer melts containing blowing agent

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.
