    摘要: Disclosed is a urethane (meth)acrylate oligomer which is obtained by reacting at least one polyoxyalkylene polyol (A), at least one monool (B1) soluble in the component (A) and/or at least one silane coupling agent (B2) reactive with an isocyanate group, at least one polyisocyanate (C) and at least one hydroxylated mono(meth)acrylate compound (D) at a ratio at which the equivalent weights of hydroxy groups, active hydrogen groups and isocyanate groups in the respective components satisfy the following formulae (1)-(3). The urethane (meth)acrylate oligomer does not substantially contain an unreacted isocyanate group. B(active hydrogen)+D(OH)=C(NCO)−A(OH) (1) 1.05≦C(NCO)/A(OH)≦2 (2) {C(NCO)−2A(OH)+2 m}×0.35≦D(OH)≦{C(NCO)−2A(OH)+2 m}×0.70 (3) In the formulae (1)-(3), A(OH) represents the total equivalent weight of hydroxy groups contained in the component (A); B(active hydrogen) represents the total equivalent weight of active hydrogen groups contained in the component (B1) and/or the component (B2); C(NCO) represents the total equivalent weight of isocyanate groups contained in the component (C); D(OH) represents the total equivalent weight of hydroxy groups contained in the component (D); and m represents the number of moles of the component (A).

    摘要: In an optical cable according to the present invention, a grooved spacer has a plurality of grooves in its circumference, and the cutting direction of the grooves is inverted at predetermined periods. Optical fibers are received in the respective grooves. On the circumference of the grooved spacer, a linear member is provided around the grooved spacer along the longitudinal direction of the optical cable at a predetermined period. The linear member is fixed to the grooved spacer by welding or bonding in the portions where they touch the outer circumferences of the grooved spacer so as to restrain the optical fibers. The linear member restraining the optical fiber to be taken out are cut in positions above the groove in which the optical fiber is received so that the required optical fiber can be taken out.
