PURPOSE: A urethane resin composition that is composed of water-insoluble and water-absorbing resin and urethane elastomer or its dope, thus having improved moisture permeability, water absorption, water resistance and antistatic property. n CONSTITUTION: (A) A water-insoluble and water-absorbing resin resulting from polymerization of (a) starch and/or cellulose and (b) polymerizable monomers that is water-soluble or can become water-soluble by hydrolysis such as acrylic or methacrylic acid is combined with (B) a polyurethane elastomer or its uncured dope. When needed, a crosslinking agent such as 2W6C alkylene glycol is added on polymerization. n EFFECT: They are sensitive to a wide range of moisture and give no uncomfortable feeling to skins. n USE: Material for inner wall of houses and cars. n COPYRIGHT: (C)1980,JPO&Japio |
