    Abstract: Aromatic polyamide having good high-temperature resistance and processing ability is obtained when the ratio of storage modulus at the glass transition temperature (Tg) DEG C to the storage modulus of a temperature of (Tg+100) DEG C is less than 3. The aromatic polyamide has a recurring unit [ -HN -Ar1 - NHCO - Ar2 - CO- ] wherein Ar1 is a divalent phenylene group represented by and Ar2 is a divalent phenylene group represented by where R is hydrogen or a methyl radical. r

    Abstract: Described herein are propylene waxes and a production process thereof. The waxes are each produced by polymerizing propylene in a reaction vessel while using a solid catalyst in the presence or absence of an organoaluminum compound. A hydrogen partial pressure of a gas phase in the reaction vessel, said gas phase being formed of the propylene and hydrogen, is maintained at 10% or higher. The solid catalyst is formed of a transition metal compound or a reaction product between the transition metal compound and an organometallic compound, an aluminoxane and a fine particulate carrier. Also described herein is a heating-roll fixing type toner composition composed essentially of a binder resin or a binder resin composition, a colorant and, as a releasing agent, the wax.
