PURPOSE:To obtain the titled molding preferable in use for a seal material or the like without mixing a thermo fluidity substance by molding and bridging a copolymer elastic body having the second order transition point above a normal temperature, heating it to more than the second order transition point to change its form and then cooling it. CONSTITUTION:A copolymer elastic body (e.g. ethylene-propylene copolymer or the like) having the second order transition point more than the normal temperature, especially a melting point of the crystal, is molded to a designed form and is bridged by a heating method or the like in the presence of a peroxide or the like. Then, after heating it at a temperature of more than the second order transition point, it is deformed by an external force so that it may form a different shape and size from the previous shape for the convenience of later use or application during the time when the molding is keeping the heat temperature more than the second order transition point. The desired molding is obtained by releasing the external force after cooling the deformation molding keeping the temperature more than the second order transition point. |
