  The present invention is directed to a method for producing an optical fiber having formyl groups on a core surface. In one embodiment, a plastic optical fiber having formyl groups on a core surface is obtained by immersing the core surface of the plastic optical fiber in a treating solution containing at least a 0.5 to 40 mM alkali metal hydroxide and a compound having formyl groups in water or lower alcohol solvent. In the other embodiment, a plastic optical fiber having formyl groups on a core surface is obtained by introducing a vic-diol group, a primary hydroxyl group or an alkenyl group on the core surface, and then oxidizing it. Turbidity on the core surface of the optical fiber thus obtained is minimized, thereby reducing the transmittance losses of light.

  本发明涉及一种生产纤芯表面带有甲酰基的光纤的方法。在一个实施例中，通过将塑料光纤的芯表面浸入至少含有 0.5 至 40 mM 碱金属氢氧化物和具有甲酰基的化合物的水或低级醇溶剂的处理溶液中，获得芯表面具有甲酰基的塑料光纤。在另一个实施方案中，通过在芯表面引入沧二醇基、伯羟基或烯基，然后将其氧化，可获得芯表面具有甲酰基的塑料光纤。这样得到的光纤芯表面的浊度最小，从而减少了光的透射损失。
