| Abstract: | Poly(ethylene terephthalate) poly(ethylene 2,6 naphthalate) copolymer (PEN PET) was synthesized by co polycondensation and kinetics of the reaction was studied.The results show that with the increase of the contents of both 2,6 naphthalate and SiO 2, the co polycondensation rate decreases and the reaction activation energy increases.PEN PET copolyester with good quality was obtained by the trial production with plant scale. |
| Keywords: | poly(ethylene terephthalate) poly(ethylene 2 6 naphthalate) copolycomdensation kinetics |
