Abstract
A water absorptive composition comprising a thermoplastic elastomer as a first component, a second component and a third component selected from the group which consists of: a water-soluble resin; a hydrophilic compound selected from the group consisting of metal salt of carboxylic acid, polyhydric alcohol, amino alcohol, linear polyether, saccharide, and sugar alcohol; and a surface treating agent selected from the group consisting of sorbitan fatty acid ester, glycidyl ether of polyhydric alcohol, and silane coupling agent. The composition is suitably used for producing a water absorptive member for protecting optical fiber elements of an optical fiber cable.
