Publication number: 20100267922Abstract: The invention relates to a method for producing a semicrystalline polymer, said method comprising the following steps: producing a polymer melt from a crystallizable polymer; shaping particles and solidifying the polymer melt, the step of shaping the particles being carried out before or after solidification; cooling the particles; treating the particles to reduce their tendency to agglomerate; crystallizing the particles. The invention is characterized in that the treatment is carried out by shaking at a temperature T1 which is below the glass transition temperature of the polymer plus 10° C., i.e. T1<Tg+10° C.Type: ApplicationFiled: September 22, 2008Publication date: October 21, 2010Applicant: Buhler AGInventors: Brent Allan Culbert, Andreas Christel, Mauricio Rodrigues
