摘要

A liquid curable resin composition for optical fibers comprising a polymer (a) having a number average molecular weight of 5,000 or more and containing at least two types of recurring ethylenic units, of which one type has a substituent group containing an ethylenically unsaturated group and the second type is substituted by a group -COOR3 (wherein R3 is a hydrogen atom or a hydrocarbon group having 1-30 carbon atoms), an aryl group, a cyano group, an alkyl group having 1-10 carbon atoms or by one or more halogen atoms.
