| Abstract: | The ozone aging characteristics of high vinyl polybutadiene (HVPB) vulcanizates was studied by ozone aging test under static tension . The results showed that the initial crack formation time of HVPB was the longest (87 min ),but the break time was the shortest as compared with those of NR , SBR and BR . The aging coefficients for tensile strength and tensile stress of HVPB decreased faster than those of NR , SBR and BR . The break time and the crack appearance of HVPB varied irregularly with the elongations applied on the samples . The ozone resistance of HVPB increased with the increase of oil amounts extended in HVPB . |
