Preparation of vinyl chloride - vinyl ether copolymers via partial etherification from PVC

Abstract

The chemical modifications of poly (vinyl chloride) with aliphatic and aromatic alcohols compounds have been investigated at room temperature and atmospheric pressure, catalysed by a new green basic catalyst, the Maghnite-K+. The presence of ether groups in the products is proven by infra red spectroscopy (IR) as well as by nuclear magnetic resonance spectroscopy (1H NMR), and characterized by intrinsic viscosity as well as by gel permeation chromatography (GPC). © BME-PT and GTE.
