PURPOSE: A sponge rubber composition having improved resistance to mold and microorganisms and durability, obtained by blending natural or synthetic rubber with a specific amount of antifungal agent and antimicrobial agent. n CONSTITUTION: Natural rubber or synthetic rubber such as SBR, IR, NBR, etc. is blended with 0.1W1.0pt.wt., preferably 0.3W0.5pt.wt. compound[e.g., 2-(4- thiazolyl)benz-imidazole shown by the formula V, etc.] shown by the formula I (R 1 is H or group shown by the formula II; R 2 is group shown by the formula III, or formula IV) based on 100pts.wt. rubber and/or 0.1W5pts.wt., preferably 0.5W2.0pts.wt. compound(e.g., sodium 2-pyridylthio-1-oxide, etc.) shown by the formula VI(M is monovalent, or divalent metal; n is 1 or 2) based on 100pts.wt. rubber, to give the desired composition. n COPYRIGHT: (C)1984,JPO&Japio |
