Abstract

In this paper, aliphatic polycarbonate (APC) was successfully prepared from low-boiling organic matter and aliphatic diols in waste electrolyte by ester exchange reaction and polycondensation reaction, and the process conditions were optimized to investigate the effects of catalyst type and dosage, type of aliphatic diol raw material, transesterification temperature, polycondensation temperature, polycondensation time, and polycondensation vacuum degree on the yield and molecular weight of the product. The structure and properties of the product APC were tested using Fourier transform infrared spectrometer (FTIR), H nuclear magnetic resonance spectra (1HNMR), differential scanning calorimetry (DSC), thermal gravity analysis (TG), gel permeation chromatography (GPC), and electronic universal testing machine were used to test the structure and properties of the product APC. The results showed that the lithium biimidazole catalyzed the best effect and the synthesized APC had the correct structure and great properties, including good thermal stability, mechanical properties, and degradation properties. The product was degraded under the action of enzyme for 12 days, and its degradation rate could reach more than 98%, meeting the use standard of degradable polycarbonate. It has a good application prospect.
