Preparation and water absorbent polymer-containing resin composition of the water absorbent polymer-containing resin composition, production method and porosity of the porous pledge pledge using the same method of manufacturing an insulated wire and insulated wire and coaxial cable

摘要

PPROBLEM TO BE SOLVED: To provide a manufacturing method for a water-containing/absorbent polymer-containing resin composition being environmentally friendly and capable of easily forming a foamed insulation body layer thin film with a low dielectric constant. PSOLUTION: A water-absorbent polymer is dispersed into water of a saturated water-absorption amount or more of the water-absorbent polymer, the water-absorbent polymer water-absorbed/swelled with water is pulverized, and the pulverized water-absorbent polymer is dispersed in a liquid-like crosslinking cured type resin.
