    Abstract: 功能性環保型樹脂是利用脂肪族二異氰酸鹽IPDI(Isophorone diisocyanate)與聚醚二醇PPG-2000 (Polypropylene glycol-2000),內含DMPA(2,2-dimethylol propanic acid)和不同分子量矽酮改質多元胺進行聚合反應,製造含矽烷鏈結和異氰酸鹽(NCO)為末端基之PU預聚合物。此預聚物為含PU之矽酮高分子化合物。另一方面使用GMA共聚物(GMA copolymer)也可與矽酮高分子進行開環架橋反應,形成壓克力之矽酮高分子。進而比較各種不同添加量矽酮改質PU樹脂與壓克力樹脂之應用性質。藉由矽酮高分子的添加量,可以量測其物理性質及熱性質。利用矽酮高分子架橋後,對於高分子的改質及應用的探討。
    The block copolymers are prepared from a NCO-terminated polyurethane(PU) prepolymers with an amino-terminated polysiloxane oligomers in various ratios. The NCO-terminated PU has been prepared by an addition reaction of isophorone diisocyanate, polypropylene glycol-2000 and dimethylolpropanic acid (DMPA) and results in a PU prepolymer with 4.0% NCO content. The polysiloxane with amino end group is commercial available with Mn=7423. The AB copolymer is resulted from a coupling reaction of these two polymers. The incorporation carboxylic group of DMPA in PU prepolymers, which provides the hydrophilic group and this carboxylic group becoming a curing site for the resulting in an aqueous-based block copolymers. The performance properties of these cured block copolymers with various polysiloxane contents are evaluated.
