    • The invention relates to an optical waveguide tube comprising a tubular cladding filled with a solid core having a higher refractive index than the cladding. In one form, a resin material having a Tg of up to 50.degree. C. and a modulus of elasticity of up to 10.sup.9 dyne/cm.sup.2 is used as the core. In another form, a copolymer of acrylic acid, methacrylic acid or a lower alcohol ester thereof with a higher alkyl (meth)acrylate is used as the core, preferably in combination with a phosphate, aromatic carboxylate, aliphatic carboxylic acid, aliphatic carboxylate or glycol. In a third form, such an optical waveguide tube is prepared by filling a hollow tubular transparent cladding having opposite open ends with a liquid monomeric charge and causing the monomeric charge to polymerize while pressurizing the exposed surfaces of the monomeric charge inwardly from the opposite open ends along an axial direction of the cladding, thereby forming a core within the cladding.
    • 本发明涉及一种光波导管,其包括填充有具有比包层更高的折射率的实芯的管状包层。 在一种形式中,使用Tg高达50℃,弹性模量高达109达因/ cm2的树脂材料作为核心。 在另一种形式中,使用丙烯酸,甲基丙烯酸或其低级醇酯与高级(甲基)丙烯酸烷基酯的共聚物作为核心,优选与磷酸酯,芳族羧酸酯,脂族羧酸,脂族羧酸酯或二醇 。 在第三种形式中,这种光波导管通过用具有液体单体电荷填充具有相对开口端的中空管状透明包层来制备,并且使单体电荷聚合,同时将单体电荷的暴露表面从相对的开口端向内压 沿着包层的轴向方向,由此在包层内形成一个芯。
