Process for the continuous production of high molecular weight
polyethylene terephthalate
摘要:
This invention relates to a process for the continuous production of high molecular weight polyethylene terephthalate by polycondensation in the solid phase wherein granulated, dried polyethylene terephthalate, having an intrinsic viscosity of at least 0.15, is first crystallized and is thereafter subjected to solid state polycondensation.
