Hydrated water-absorption polymer containing resin composition, porous body and insulated wire using same, method of making the wire and coaxial cable

摘要

A hydrated water-absorption polymer containing resin composition includes a liquid cross-link curable resin composition, and a water-absorption polymer dispersed in the liquid cross-link curable resin composition. The water-absorption polymer is preliminarily hydrated and swollen. The water-absorption polymer before being hydrated and swollen includes an average particle diameter of not more than 10μm. The water-absorption polymer includes an amount of water absorption of 10 to 100 g/g.
