Abstract
PURPOSE: The titled rubber composition that is composed of natural rubber and a water-insoluble, water-absorbing resin which is obtained by polymerizing a polymerizable monomer with starch or the like which is incompatible with the natural rubber, thus being suitably used in civil engineering and house building , because of its improved water-swelling properties and good sealing.
CONSTITUTION: The objective composition comprises (A) natural and/or synthetic rubber and (B) a water-insoluble, water-absorbing resin which is obtained by polymerizing or allowing a polymerizable monomer such as acrylic or methacrylic acid, preferably further a crosslinking agent such as 2W6C alkylene glycol to react with starch and/or cellulose, preferably at a ratio of 1 : (0.01W1).
USE: Packing gasket for preventing water leak in car devices and electric appliances.
