A literature survey was conducted on SBR aging, Being vulnerable to attack by the forces of nature (such as ozone, oxygen, heat and light), SBR vulcanizates requires the addition of chemicals to retard aging. Phenylamines were found to be the best type of antiaging additives, The effectiveness of other antiaging additives were examined. Although the mechanisms of aging are not perfectly understood; sane theories and aging reactions are discussed.
