ABSTRACT:
There is provided an ethylenically unsaturated lower carboxylic acid metal salt-containing rubber composition having good mold releasability.
This rubber composition is composed of preferably 5 to 100 parts by weight of an ethylenically unsaturated lower carboxylic acid salt preferably and 1 to 10 parts by weight of a higher fatty acid metal salt compounded with 100 parts by weight of rubber. Preferably 20 parts by weight or less of zinc oxide may further be compounded thereinto.
Compared with conventional vulcanizates prepared using a mold coated with a mold release agent and vulcanizates prepared from a rubber composition to which silicone oil or the like was added, vulcanizates from the present rubber composition are ones wherein lowering of characteristics such as strength due to inclusion of these compounds is small and which have improved mold releasability.
