The environmental and sustainability problems currently faced worldwide call for the research on renewable materials across the industry. We successfully synthesized furan-based co-polyester with different mole ratio of FDCA and TPA. And we investigated the effect of three types of catalysts for TBT, TIS, and Sb2O3 and their content on the degree of polymerization. In particular, it could be found that the vacuum history influence upon the number average molecular of co-PEF in the polycondensation step. Additionally we try to check crystallinity of some co-PEFs with same molecular weight, which is closely relative to the their barrier property. |
