Abstract

PURPOSE: To prepare a foamed material having very high elasticity, by impregnating and fixing an impregnating agent having an active hydrogen group in a foamed material, and then reacting with a specific liquid prepolymer, thereby remarkably increasing the amount of the soft segment.
CONSTITUTION: A foamed material is coated with or dipped in a dissolved or molten impregnating agent (A) which has an active hydrogen group and is solid at normal temperature, e.g. trimethylolpropane, etc. The impregnating agent (A) is impregnated and fixed in the foamed material. The treated foam thus obtained is dipped in a liquid polyurethane prepolymer (B) having free isocyanate groups, squeezed e.g. with rolls, and heated to react the component (A) with (B) and to obtain the objective foamed material.
USE: Interior material and cushioning material.
