METHOD FOR THE PRODUCTION OF POLYESTER GRANULES LOW IN HYDROLYSIS MADE OF HIGH-VISCOSITY POLYESTER MELTS, AND DEVICE FOR THE PRODUCTION OF THE POLYESTER GRANULES

摘要

The present invention relates to a method for the continuous production of polyester granules low in hydrolysis made of high-viscosity polyester melts, characterized in that the decrease in the degree of polycondensation from the polyester melt to the polyester granule is less than 2%. The invention further relates to a polyester granule produced by said method, and to a device for the production of the granule.
