摘要

本文主要探討含苯環改質單體（對苯二甲酸TPA、間苯二甲酸IPA、對萘二甲酸NDA）在聚合反應工程中取代AA不同比例，對半芳香族改質聚醯胺聚合物物性變化的情形。結果顯示，共聚合物熔點Tm與熱裂解溫度Td5因改質單體差異而有不同結果，而熱焓（ΔH）則有隨著改質單體添加比例增加而有減少的現象。

並列摘要

This study was mainly discussed the physical properties of semi-aromatic modified polyamide polymer which the AA was substituted by different mole ratio of Terephthalic acid (TPA), Isophthalic acid (IPA) or 2,6-Naphthalic acid (NDA) during condensation polymerization. The results show that the melting temperature (Tm) and decomposition temperature (Td5) of copolymer were changed when different mole ratio of AA was substituted by TPA, IPA or NDA. It's clearly that the enthalpy (△H) was reduced with increasing the mole ratio of TPA, IPA or NDA.
