Abstract:
1. A process for producing polyamide particles, the process comprising: anionically polymerizing a lactam in the presence of a catalyst and an activator by introducing discrete droplets of a reaction mixture comprising the lactam, the catalyst, and the activator into a surrounding gas phase within a reactor, and reacting said reaction mixture to form polyamide particles, wherein the introducing and mixing of the lactam, the catalyst, and the activator occurs continuously, such that: wherein the introducing of the lactam, the catalyst, and the activator into the reactor is carried out by spraying the mixture of the lactam, the catalyst, and the activator through spray nozzles at a rate of from 0.1 to 10 m
