| 中文摘要: |
| 对比研究日本产AR74，AR840和国产AR100，AR96四种牌号的丙烯酸酯橡胶（ACM）的结构和性能。结果表明：4种胶均为丙烯酸丁酯橡胶；AR100和AR96的相对分子质量和物理性能相近，生胶拉伸强度和门尼粘度高于AR74和AR840；AR74，AR840，AR96和AR100的玻璃化温度依次升高，热稳定性依次变好；采用相同的皂/硫黄硫化体系时，AR840的硫化程度最高，AR100和AR96硫化胶的物理性能优于AR74和AR840硫化胶。 |
| 英文摘要: |
| The structure and properties of four types of acrylic rubber(ACM) were compared，in which AR74 and AR840 were made in Japan，while AR100 and AR96 were made in China.The results showed that the four ACMs were all butyl acrylate rubber.The molecular weight and physical properties of AR100 and AR96 were similar，and their green strength and Mooney viscosity were higher than those of the other two types of ACM.The glass transition temperature of those ACM increased in the order of AR74，AR840，AR96 and AR100，and the thermal stability was also getting better in the same order.With the same soap/sulfur curing system，the vulcanization degree of AR840 was the highest，and the physical properties of AR100 and AR96 were better than those of AR74 and AR840. |
