Abstract : The physical and mechanical properties of a series of random copolymers of SiB-1 and SiB-2 were investigated. Modulus-temperature data yielded Tg, the glass transition temperature, Tm, the melting temperature, and Tox, the temperature of rapid oxidative crosslinking. Stress relaxation and weight loss data were also obtained on selected copolymers. These copolymers all have outstanding high temperature properties, which improve with lowered SiB number. (Author)
