ELASTOMERIC AND MECHANICAL PROPERTIES OF POLY-M-CARBORANYLENESILOXANES.
Abstract
A new high-temperature elastomer, SiB-2, was investigated by stress relaxation, modulus-temperature, and volume-temperature techniques. SiB-2 was found to be more stable than a related elastomer, radiation-cured silicone rubber, having about twice as long a chemical relaxation time at 250 C. Possible mechanisms to account for this increased stability are discussed. At low temperatures, the glass transition temperature for SiB-2 was estimated at -34 C, which compares well with the inflection temperature of 30 C for this polymer. The melting transition temperature for SiB-2 was estimated to be +56 C. (Author)
