PEN啤酒瓶的开发应用

The study and application on preparation of PEN beer bottle

研究了2,6-萘二甲酸二甲酯(DMN)缩聚为聚2,6-萘二甲酸二乙酯(PEN)共聚物的合成工艺,讨论了PEN化学性质和气体阻隔性能。结果表明:PEN共聚物的合成工艺与普通聚酯切片的合成工艺相近,PEN的啤酒瓶可耐100℃高温,对O2、CO2气体的阻隔性比普通PET瓶提高6倍以上。

Poly(ethylene 2, 6-naphthalate) was prepared with DMN, PEN physics,chemical characters and gas proofness was discussed in this paper. The results showed that the polymerization of PEN was similar to that of ordinary PET chips,the PEN beer bottle could endured high temperature of 100 ℃. Its proofness of O_2 and CO_2 were 6 times more than ordinary PET bottle.
