Title Structure and Properties Of Bromobutyl rudders
Abstract
Structure and properties of the different grades of bromobutyl rudder have been studied in this work. The methods of 1H-NMR and mooney viscometer were used in this study to investigate bromine content and mooney viscosity respectively, and we also studied the performance of different grades of bromobutyl rudder vulcanizates, which involved cure properties, mechanical properties and thermal properties. Compared with a series of performance, we find that the bromine content of the bromobutyl rudder which made in China is the highest, and for the 2255 brominated butyl rudder, mooney viscosity is the largest. The cure rate of the 2255 brominated butyl rudder is the fastest, and the slowest is the one made in China. For the mechanical properties, the best one is the 2255 brominated butyl rudder, which also has better tensile strength and tear strength. Moreover, the thermal stability of the various grades of bromobutyl rudder vulcanizates are similar, but it has improved greatly compare to the raw rudder. The glass transition temperature of the various grades of bromobutyl rudder are basically similar.
