A LOW-TEMPERATURE DIFFERENTIAL THERMAL ANALYSIS OF HYDROXY-TERMINATED AND CARBOXY-TERMINATED POLYBUTADIENE.
Abstract
A low-temperature differential thermal analysis of hydroxy- and carboxy-terminated polybutadiene was performed with varying amounts of n-butylferrocene. No distinct phase changes were observed to indicate that the sample components became separated during cooling. However, the slow transformation into the glassy state was observed, yielded glass transition temperatures of -80 to -95C. This is far below the low temperature specification for these propellants. This analysis yielded no evidence of a physical or chemical transition that might cause a low-temperature firing failure in the finished propellants. (Author)
