摘要：
The present invention relates to a process for the continuous discharge of pre-classified polymer particles, particularly rubber particles, from a gas phase polymerization reactor, comprising the steps of classifying the polymer in a classifier, discharging the particles with a sufficient size and conveying the undersized particles back into the gas phase polymerization reactor.
