Computer controlled apparatus for preparation of polyethylene terephthalate

摘要

A computer controlled apparatus for the preparation of high molecular weight, high quality polyethylene terephthalate polyester suitable for processing into fibers, films, and other shaped articles. The computer is interrelated with a hardware system in such a manner that it is capable of initiating process changes capable of producing a predetermined intrisic viscosity polymer during the polycondensation reaction stages.
