本研究以新開發的Al(Tralen) 有機鋁金屬錯合物及Tralen化合物 (2,2'-(1,2-phenylenebis(azanediyl))bis(cyclohepta-2,4,6-trien-1-one))做為控制劑來調控不同單體的可控/活性自由基聚合反應。Al(Tralen)及Tralen化合物對非共軛單體醋酸乙烯酯的聚合反應分別都有良好的控制效果。在反應過程中，聚醋酸乙烯酯的分子量隨著轉化率呈線性增長並和理論分子量相符，我們也藉由鏈延伸反應來確認尾端官能基的活性。此篇論文為首次利用鋁錯合物調控醋酸乙烯酯的研究。
同時，我們也嘗試以Al(Tralen)以及Tralen化合物來調控其他工業上常見的單體，如苯乙烯、乙烯正丁醚、丙烯酸甲酯、甲基丙烯酸甲酯、丙烯腈及N-乙烯基吡咯烷酮的自由基聚合反應，其中Tralen化合物對丙烯酸甲酯、N-乙烯基吡咯烷酮及丙烯腈有些許的控制效果。我們進一步以PVAc-Tralen做為大分子起始劑成功合成出PVAc-b-PMA嵌端共聚物。
Controlled/living radical polymerization (C/LRP) of vinyl acetate (VAc) was first achieved by the mediation using aluminum complexes of Al(tralen) and Tralen compounds (Tralen compounds is 2,2'-(1,2-phenylenebis (azanediyl))bis(cyclohepta-2,4,6-trien-1-one)). The living characters of VAc polymerization were demonstrated by the linear growth of molecular weight with monomer conversion, moderate molecular weight and chain extension experiment. In addition, Tralen compounds could also mediate the C/LRP of methyl acrylate (MA), acrylonitrile (AN) and N-vinyl pyrrolidone (NVP). Moreover, the block copolymer PVAc-b-PMA had been successfully obatined by using macro-initiator of PVAc-Tralen.
