For the wood preservation, controlling of deterioration of wood is very important. Deterioration is the phenomena that wood cell structure is destroyed by the action of enzymes produced by microorganism. Therefore, it must be the important research theme to confrol and prevent the deterioration of wood. In this research, I synthesized a various kinds of fluoroalkylated oligomenc agents and applied for cellulose as a model of wood to control the deterioration of wood by adding the water-repellency on the surface.As a result, the follwings were clarified :(1) Fluoroalkylated oligomers having trimethoxysilyl or blocked-isocyanate groups can improve the water-and oil-repellency of a lot of surfaces, such as glass, cellulose, polyster and so on.(2) Co-oligomers having cationic segments, ammonium and/or Phosphonium, showd the high anti-bacterial activity against Staphyloccus aureus etc. as well as water-and oil repellency.(3) Co-oilgomers having phosphonium segments also showed strong anti-fungal activity.(4) Co-oilgomers having ammonium segments showed termites-killing activity.(5) Co-oilgomers having phosphonium segments and trimethoxysilyl or blocked-isocyanate groups was found to be applicable as the surface fixing agents.Actually, block-isocynanatc co-oilgomers having phosphonium segments showed the strong ability to control deterioration of wood.

对于木材防腐来说，控制木材的劣化是非常重要的。变质是木材细胞结构在微生物产生的酶的作用下被破坏的现象。因此，控制和防止木材的劣化必然成为重要的研究课题。本研究合成了多种氟烷基化低聚物，并将其应用于纤维素作为木材的模型材料，通过增加木材表面的拒水性来控制木材的劣化，研究结果表明：（1）含三甲氧基硅基或封端异氰酸酯基的氟烷基化低聚物可以改善玻璃、纤维素、聚酯等多种表面的拒水拒油性。(2)具有阳离子片段、铵和/或膦的共聚低聚物显示出对金黄色葡萄球菌等的高抗菌活性以及拒水和拒油性。(3)具有鳞片段的共油聚物也显示出强的抗真菌活性。(4)具有铵片段的共油聚物显示出杀白蚁活性。(5)含膦链段和三甲氧基硅基或嵌段异氰酸酯基的共高分子可用作木材表面固定剂，含膦链段的嵌段异氰酸酯共高分子具有较强的控制木材劣化的能力。
