• 中文摘要： 在触媒三乙撐二胺(Triethylenediamine, TEDA)存在下，二氧化碳可與丙烯?發生共聚合反應而生成含酯結構之共聚合體。當触媒使用量少時所得聚合體為透明粘稠物，而触媒使用量多時所得聚合體為固體粉末。其紅外線光譜於1690 cm-1顯示極強之-COO-特性吸收。從元素分析可知聚合體含二氧化碳，並推測二氧化碳與丙烯?之共聚合反應機構是經由兩性離子(zwitterion)聚合，這是由來於二氧化碳與三乙撐二胺反應生成之中間體氨基甲酸酯(Carbamate)於高溫時開環聚合而得。本文並對聚合過程中，触媒量之效果、聚合時問、聚合溫度、二氧化碳使用量加以探討。
• 英文摘要： Carbon dioxide was found to copolymerize with acrylonitrile to give polymer of ester structure in the presence of triethylenediamine. The copolymer was a transparent viscous polymer when polymerized at a low catalyst level, but solid at the high catalyst level. The IR spectra of copolymer exhibits a strong ester(-COO-) band at 1690 cm-1. From elemental analysis it was found that the copolymer contained carbon dioxide. The effect of catalyst, polymerization temperature, polymerization time and the amount of carbon dioxide on the process were investigated. The mechanism of the copolymerization of carbon dioxide and acrylonitrile is proposed to involve zwitterion polymerization via initiation by the ring-opening of carbamate in high temperature. The carbamate is an intermediate of the reaction of amine and carbon dioxide.
