What is Advances in Makrolon 2417 Recycling about?
This document summarizes the production process of virgin polyethylene terephthalate (PET). It begins with an esterification or trans-esterification reaction to form bis(hydroxyethyl) terephthalate, followed by pre-polymerization and polycondensation to increase the degree of polymerization. For applications requiring high molecular weight PET, solid state polymerization is used to further increase the degree of polymerization and molecular weight. Virgin PET is a stiff polymer above its glass transition te
