Recent advances in the synthesis and applications of poly(1,4-dioxan-2-one) based copolymers

Abstract

The review provides the recent advances in the synthesis, properties and applications of poly(1,4-dioxan-2-one) (PPDX). PPDX represents a promising candidate as a biodegradable substitute, because of its interesting thermomechanical properties such as a melting temperature of 110°C. This poly(ester-alt-ether) copolymer can be useful materials not only for medical use, but also for general uses as films, molded products, laminates, foams, nonwoven materials, adhesives and coatings for temporary more universal uses. However, little attention has been paid to the synthesis and properties of PPDX. The main reasons are that its monomer, 1,4-dioxan-2-one, was not commercially available in the past, but also the low ceiling temperature of PPDX (265 °C) favors the unzipping depolymerization reactions in the molten state. Hence, the recent improvements in terms of activity and productivity will be discussed according to the key-parameters governing the synthesis and melt-processing of PPDX. Besides, the properties and applications of PPDX are given.
