本文以dicyclopentadiene (DCPD)為起始物，利用Diels-Alder 加成反應合成出兩種不同長脂肪側鏈之降冰烯單體，並以dichloromethane為溶劑以及[1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene]dichloro(phenylmethylene) bis(3-bromopyridine) ruthenium(II) (G3)進行活性開環複分解聚合反應，成功合出一系列擁有嵌段共聚物結構的聚降冰烯高分子(rPNB)。接著利用5‐butylbicyclo[2.2.1]hept‐2‐ene (M1)以及5‐(bromopropyl)bicyclo[2.2.1]hept‐2‐ene (M2)兩者親疏水單體進料比的不同，控制其IEC值(0.76~2.25 mmol/g)，將不同IEC之高分子進行還原和四級銨化，最後以N,N,N′,N′-tetramethyl-1,3-diaminepropane (TMDAP)作為交聯劑，成功以溶液澆鑄法製成不同IEC以及交聯程度之陰離子交換膜，並對其做燃料電池性質之探討。
由於其四級銨鹽本身之熱穩定性，使得薄膜在200 oC前皆無出現熱重損失，展現出極佳的熱穩定性。而調整不同IEC以及交聯含量所測得含水率和溶脹率分別為21 %至140 %以及2.1 %至23.1 %之間。而本次最高IEC值之CL10-1.91HPNB進行離子傳導率之測試，在IEC值為1.91 mmol/g且溫度80 oC下，離子傳導率可達122.54 mS/cm，而適當交聯含量之CL15-1.19HPNB在IEC值為1.19 mmol/g且溫度80 oC下，其離子傳導率也有110.37 mS/cm，證明適當的交聯有助於提升離子傳導率以及相分離性，最後藉由在60 oC之1 M KOH中進行鹼性穩定性之測試，並在720小時都未發現明顯降解，顯示極佳的鹼性穩定性，但過多的交聯含量，則會導致鹼穩定性產生下降。

In this work, we used dicyclopentadiene (DCPD) as a starting material and synthesized two kind of norbornene with different long aliphatic side chains by Diels-Alder reaction. And we seuccessfully synthesized a series of polynorbornene with block copolymer structure by using [1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene] dichloro(phenylmethylene) bis(3-bromopyridine) ruthenium(II) (G3) and controlled the IECs and crosslinking degree of the anion exchange membrane (AEM) by feeding ratio.
The membrane has excellent thermal stability and the water uptake and swelling ratio were measured by adjusting different IEC and crosslinking degree are 21 % to 140 % and 2.1 % to 23.1 %, respectively. The CL10-1.91HPNB which has the highest IEC value was tested for conductivity. When the IEC value is 1.91 mmol/g and the temperature is 80 oC, the conductivity can reach 122.54 mS/cm. The conductivity of CL15-1.19HPNB with appropriate crosslinking degree is 110.37 mS/cm, which prove that proper crosslinking can help to improve conductivity and phase separation. Alkaline stability were tested in 1 M KOH solution at 60 oC for 720 hr. The alkaline stability of the membrane was excellent with no detectable degradation in conductivity after 720 hr in 1M KOH at 60 oC,but high crosslinking content will reduce the alkaline stability.
