The present invention relates to a polymeric foaming agent including sulfonyl hydrazide and a method for producing the same. More particularly, the present invention relates to a polymeric foaming agent including sulfonyl hydrazide and a method for producing the same wherein methacryloyl oxybisbenzenesulfonyl hydrazide (MAOBSH), a novel monomer including a functional group of sulfonyl hydrazide capable of forming a foaming body by being decomposed with heat, is synthesized from methacryloyl chloride and 4,4′-oxybisbenzenesulfonyl hydrazide(OBSH). In the method of the present invention, a poly(MAOBSH) which is a polymeric foaming agent (PFA) is obtained using AIBN, an initiator, in the existence of a solvent THF at 70°C and the foaming body, in which the polymeric foaming agent is mixed, exhibits a more superior surface and cell structure in which OBSH is mixed and has excellence mechanical properties such as elongation and compression set, so that the polymeric foaming agent and the method for producing the same of the present invention has characteristics of improving the compatibility with the polymeric materials. |
