Abstract

Process of preparing high molecular weight poly, polycondensation of ethylene poly) with a relative viscosity lower than 2.35 characterized by solidifying a polyethylene terephthalate of not more than 1.65 in the liquid phase and keeping it in the form of particles an elevated temperature and a combined partial pressure of the reaction products not less than 2 mm. Of mercury until the degree of increase in the relative viscosity is reached. (Machine-translation by Google Translate, not legally binding)
