Abstract

Abstract: The effects of synthetic conditions on the synthesis of polyethylene naphthalate (PEN) from the polycondensation of BHEN via transesterification between 2,6-naphthalene dicarboxylate (NDC) and ethylene glycol (EG) were studied. With zinc acetate as catalyst and steric phenol Weizufen 1010 as antioxidant, the transesterification reaction conditions of NDC with EG and processing conditions for BHEN polycondensation were optimized by orthogonal experimentation.

Key words: 2,6-naphthalene dicarboxylate, transesterification reaction, polycondensation, polyethylene naphthalate
