PURPOSE:To obtain a rubber composition, having reduced offensive smell in processing and molding rubber with various compounding agents and capable of providing an odorless rubber composition itself, by blending a deodorant compound containing a compound having acid anhydride in the molecule with the rubber. CONSTITUTION:A deodorant component-containing rubber composition, obtained by blending 100pts.wt. rubber (e.g. natural rubber, SBR or BR) with 0.05-30pts. wt., preferably 0.1-20pts.wt. compound having acid anhydride group in the molecule, e.g. aromatic polycarboxylic acid anhydride (e.g. phthalic anhydride), acrylic acid based polymer having acid anhydride crosslinkages (polymer having >=1mol.%, preferably 5mol.% acid anhydride groups), Diels-Alder reaction type addition reaction product (derivative) of an alpha,beta-unsaturated dicarboxylic acid anhydride (preferably maleic anhydride) with olefins, etc., and, as necessary, adding various rubber additives. |
