RESIN COMPOSITION SWELLING WITH WATER

摘要

PURPOSE:A composition that is obtained by adding a nonionic surfactant of ethylene oxide condensation product to a mixture of a high water-absorbing resin and an elastomer, thus giving moldings good in both water absorption and rapid expansion by extrusion. CONSTITUTION:100pts.wt. of a resin composition containing a high water-absorption resin and an elastomer, are added to 0.5-20pts.wt. of a nonionic surfactant of ethylene oxide polycondensation product. The weight ratio of the water-absorption polymer to the elastomer is 30/70-70/30. An example of the nonionic surfactant is water-soluble polyoxyethylene alkyl ether.
