Abstract

Abstract: The polyesters with high T g (≥100°C) and good clarity are desired in fabricating heat‐resistance containers such as baby bottles, cups, medical apparatus, and kitchen appliances. In this work, a series of poly(butylene bis[4‐(2‐hydroxyethoxy) phenyl] sulfone 1, 4‐cyclohexanedimethylene 2, 5‐furandicarboxylate) (PBSCFs) that show superior thermal and mechanical properties against current bio‐based polyesters were synthesized via a melt polycondensation method. The accurate chemical structures of PBSCFs were confirmed by 1 H‐NMR and 13 C‐NMR. The SEC results show that PBSCFs have number averaged molar mass ( M n ) in the range of 9700–28, 500 g/mol. The T g of PBSCFs increase from 94°C for PBSF to 108°C for PBSCF‐50 as the increasing of CHDM unit. Meanwhile, the ductility of PBSCFs also improved with the elongation at break of PBSCF‐40 increased to 223%. In addition, the PBSCF‐40 sample reported in this paper shows thermal decomposition temperature of 427°C, transmittance of 84.6%, haze of only 0.17%, tensile strength of 74.1 MPa, and tensile modulus of 2287 MPa.
