DEVELOPMENT OF RUBBER GASKETS WHICH ARE RESISTANT TO NUCLEAR RADIATION. Final Report. Report No. 149-4
Gamma irradiation effects on vulcanized rubbers (vulcanizates) are studied for doses up to 109 r. The tendency of vulcanizates to undergo compression set, when exposed to radiation while under compression, is chosen as a measure of the effect of the radiation. The radiation effects are smallest on vulcanized natural rubber, styrene/butadiene copelymers, and acrylonitrile/ butadiene/methacrylic acid terpolymers. The resistance of these vulcanizates to radiation can be increased by compounding the rubbers with certain antioxidants or antiozonants, and/or with certain chemicals containing aromatic rings or condensed ring structures. The resistance of a styrene/butadiene vulcanizate to radiation is increased by the use of dicumyl peroxide instead of sulfur as the vulcanizing agent. (T.T.H.)
