发明名称 Controlling the crystallization of polyesters by means of their water content
摘要 Methods are disclosed herein to reduce and/or eliminate agglomerations and deformations of pellets comprised of crystallizable thermoplastic polymer material during a crystallization or crystallization of the pellets. As described herein, polymer material is subjected to one or more conditioning steps prior to crystallization, in which a controlled moisture content and/or controlled moisture profile is set in the material, or in which the polymer material was obtained via solidification from a polymer melt in such a way that the polymer material has a defined initial moisture profile before the crystallization step
