| Abstract: | Abstract BHEN intermediate was synthesize via transesterification between NDC and EG and the effect of processing conditions on synthesis of PEN was studied via BHEN polycondensation and by using orthogonal experiment method. Zinc acetate was optimized as the catalyst and steric phenol WZF1010 as the antioxidant and the optimum processing conditions for BHEN polycondensation are as follows: reaction temperature 568 K, the catalyst concentration is about 4×10-4 mol pet one mol of BHEN, reaction time 180 minutes and the antioxidant concentration is about 1×10-5 mol pet one mol of BHEN. |
