| Abstract: |
| 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. |
