The present invention relates to a process for introducing strain-induced crystallization to polyesters. Specifically, amorphous polymer from the melt phase reactor is first extruded through a traditional strand die. However, instead of going directly into a pelletizer/cutter, it is stretched uniaxially...http://www.google.es/patents/US6159406?utm_source=gb-gplus-sharePatente US6159406 - Process for rapid crystallization of polyesters and co-polyesters via in-line drafting and flow-induced crystallization
