近年來,超分枝聚合物 (hyperbranched polymer) 材料廣泛發展並應用於多種領域,主要原因為超分枝聚合物具有高度分枝的特點,如低黏度、高溶解度與末端多官能基等優點。而超分枝材料普遍面臨結構上,大量的分子末端造成低熱穩定性,因此,將具高熱穩定性之聚亞醯胺 (polyimide) 導入,製備出超分枝狀聚合物為此實驗要務。

過去文獻中,對於聚亞醯胺的研究,大部份是克服亞醯胺官能基低溶解性之缺點。為同時兼具高熱穩定性與低成本,本研究利用新型聚合方式-連續自我反覆反應,進行 A2B3 超分枝狀聚合物的製備。單體方面,藉由高產率的硝基取代、水解、脫水以及甲醇加成開環反應,自行製備出具高溶解特性之雙羧酸 (bicarboxylic acid) 官能基之反應單體與三羧酸 (tricarboxylic acid) 官能基之反應單體。高分子製備以雙異氰酸鹽 (4,4’-methylene diphenylisocyanate, MDI) 單體作為起始原料,利用氧化磷催化劑進行聚合,並添加雙羧酸或三羧酸單體,製備出中間體 polyacylureas,acylurea 結構提供材料高溶解性、高成膜性與良好加工性,對往後材料的後續加工有極佳的優勢。將 polyacylureas 進行連續自我反覆反應後,即可獲得線性或超分枝狀聚亞醯胺高分子。由於材料在固態高溫情況下進行反應,提昇材料的熱穩定性與抗溶劑性。因此,相較於一般文獻方式,新型連續自我反覆反應之材料,其熱性質有明顯的提昇。

In recent years, dendritic macromolecules have drawn considerable interest because of their unique physical and chemical properties, such as low solution viscosity, high solubility, and a large number of terminal functional groups. The hyperbranched feature would effectively suppress molecular motion. The resulted materials will certainly exhibit excellent processing capacity, which enable the fabrication of high quality thin films for applications. However, the thermal stability of hyperbranched polymers is often at issue.

Aromatic polyimides are important commercial polymers possessing outstanding thermal stability along with other excellent properties. However, commercial applications for polyimides are often limited due to low solubility, poor processability, rigidity, and/or high viscosity even at high processing temperature. To overcome these shortcomings, a novel synthetic methodology of sequential self-repetitive reactions (SSRR) was used to prepare the polyimide consisting of hyperbranched conformation. This SSRR is based on aryl carbodiimide (CDI) chemistry. The diisocyanate group of 4,4'-methylene diphenylisocyanate was reacted to form a polycarbodiimide, and subsequently a triaromatic acid was reacted with the polycarbodiimide to obtain an intermediate, polyacylurea. The polyacylurea exhibited excellent organosolubility, which enabled the fabrication of high quality thin films. The acylurea moieties were then converted to imide structures via SSRR, and the Tgs of the hyperbranched polymers would be elevated significantly. For comparison, a biaromatic acid was used to prepare a linear polyimide using the similar methodology.

Thermal stability of the hyperbranched polymers via SSRR were better than the one synthesized via the reaction of 4,4''-methylenedianiline and 1,1,1-Tris(4-carboxy-3-methoxycarbonylphenoxy)ethane. Moreover, high yields of the hyperbranched polyimides were also achieved in this work.
