Studies on the Prevention of Polymer degradation by Ozone (part 1, Effect of Reactive Antioxidant)

오존에 의(依)한 고분자(高分子)의 해중합방지연구(解重合防止硏究), 오존화방지제(化防止劑)의 각탄성체(各彈性體)에 대(對)한 효과(效果) (제1보(第1報))

1. The effect of reactive type antioxidant, G-1 in comparism to ordinary antioxidant, SP, which are used for NR and SBR has teen studied, and its recipes are equal. The effects against ozone aye been shown that ill ordinary antioxidant, SBR, no an particular effect both for NR and SBR was found, where as in reactive type, considerable influence was recogniged particulary in dynamic ozone test. 2. The influence of reactive antioxidants on velcanization has been studied by means of Mooney viscometer and Rheometer. 3. The ageing properties of vulcanizates containing reactive antioxidant have been studied in terms of tensile strength.
