PURPOSE:To improve the heat resistance and compression modulus of elasticity of a molded body by a method wherein specified polyacrylic metal salt power is filled in to a mold and, after that pressed into a shape under specified pressure and temperature. CONSTITUTION:Poder of polyacrylic metal salt, the metal of which consists of 10-100% by mol of quadrivalent metal and 90-1% by mol of monovalent and/or bivalent and/or trivalent metal, is filled into a mold and, after that, is pressed into a shape under a pressure which is 100kg/cm<2> or above and 1000000kg/cm<2> or below, and a temperature which is lower than the melting point of the polyacrylic metal salt. The atmosphere during the pressing may be any gas such as nitrogen gas, helium gas, air or the like. The pressing is preferably done under the reduced pressure. The form of a molded body is any form such as bar form, plate form or the like. The obtained molded body has high modulus of elasticity and can be heat-treated, turned, cut off, bored and the like, when necessary. |
