Integrating Chinese Technology with American Ideals

Biodegradable Copolyester
New One Step Method for Synthesis

Introduction

This technology is a one step method for synthesis of a biodegradable copolyester. In this one-step method, both monomers of bishydroxyethylene terephthalate (BHET) andE-capralactone (E-CL) were used as raw materials, and tetra-n-butyle titanate (Ti(OBu)₄ was used as a catalyst.

Our Technology

The copolycondesnation was performed at 160~220ºC for 0.5~5.0hrs and then under a reduced pressure of 6.66 x 10^-6~ 2.66 x 10^-4 Mpa at 230~270ºC for 0.5~8.0hrs.

Properties

This new method pioneered by our scientists has the following properties:

Simple PolymerizationTechnology

Shorter Polymerization Processing Time

Reduced Equipment Demands

Controlled chemical reactions

Steady product composition and properties

This Method is Suitable for Industrial Production
