Abstract

Inventia se refera la un procedeu de reglare a maselor moleculare ale polifenilenoxidului obtinut prin reactia de polimerizare oxidativa în solutie a 2,6-xilenolului, în mediu de hidrocarburi aromatice, prin aditionarea controlata a unor bisfenoli, agenti de frânare a cresterii maselor moleculare.The invention relates to a process for adjusting the molecular masses of polyphenylene oxide obtained by oxidation polymerization reaction in a solution of 2,6-xylenol in an aromatic hydrocarbon medium by the controlled addition of bisphenols, braking agents of molecular weight growth.
